Everything you need to know to pass the exam. How to pass the OGE in the Russian language: tips and tricks. What is it about

Cheat sheets, of course, can help pass exams. Here are some tips for making them.

1) "Regular cheat sheet"
An ordinary sheet of paper is taken, on which formulas and answers to questions are written in small text. It is best to divide a sheet of paper into several parts so that each part fits freely into the pocket.
It can be quite difficult to write off from such a cheat sheet, because teachers can easily notice it. It is best to sit in the middle or at the end of the class.
2) "Invisible Cheat Sheet"
Take two sheets of paper. We put one sheet under the second sheet. On the top sheet with a pen, write the necessary formulas and answers. You have to push harder on the handle. The top scribbled sheet can be thrown away. Everything that you wrote is left on the bottom sheet of paper, you just need to catch the best viewing angle and write off everything you wrote.
3) "On an elastic band"
The answer is written on a small sheet of paper, on the reverse side of which the end of a thin elastic band is attached with tape, the other end is tied to the hand. When the teacher approaches dangerously, the piece of paper is released, to which the rubber band immediately reacts and hides the cheat sheet in the sleeve.
4) "Calculator"
The necessary information is entered into an electronic notebook, similar to a calculator. In exams where a calculator is needed, such a notebook does not cause much suspicion.
5) "Diskette"
On a 1.44 floppy disk, you need to move the metal flap and write the necessary information on the internal disk with a pen or felt-tip pen. Then assemble the diskette back and the cheat sheet is ready. During the exam, the floppy disk is placed on the table and, when necessary, the metal flap is moved away and the disk rotates from below. Additionally, you can stick something on top of the floppy disk, and make markings on the side, as on a ruler, so that the question: “What is this?” , - one could confidently say: "New line".
6) Hand free
Hands free system, wired or Bluetooth is connected to the mobile phone. During the exam, a call is made to a partner who will dictate the answer. This method is most convenient for girls with long hair - the hair covers the earpiece.
7) "Rolled"
It is printed on toilet paper. To do this, you need to dial small print text, then print it on thick toilet paper. The advantage of the method is that all questions can be placed on a small piece. If the teacher notices cheating, you need to quickly roll the toilet paper, show it and ask to leave. In the toilet for 5 minutes you can learn or repeat the question. The best place for such a cheat sheet is the inside pocket of a jacket or a trouser pocket.
8) "Player"
The necessary information is recorded on the player. At the exam, the player turns on and with the help of the playlist, the desired answer is found. But any player and any headphones in the exams are suspicious. To write off from such a cheat sheet, you need to choose a position closer to the end of the class and next to the window. It is not recommended to sit on the last desk. You can lean on the window, hold the headphones with your hands and pretend to think.
9) "Ruler"
All the formulas and answers you need are written on the ruler. It is advisable to disguise them with drawings or inscriptions so that a passing teacher does not set you on fire.
10) Upskirt
You will need: stockings, preferably not very dark, a pen, a piece of paper.
We write a cheat sheet on a piece of paper and put it under stockings. During the exam, we modestly lift our skirt and look.
It is recommended to put the cheat sheet closer to the genitals, because the teacher will not dare to look under your skirt.
11) "Crib for girls"
You can write on your nails with a helium pen and then cover your nails with clear polish. It will look as if the nails were just painted in a pretty blue color.
12) "Calculator"
We write a cheat sheet on the back of the calculator with a simple pencil. At the exam, we put the calculator on the table and calmly write off it.
13) "Tongue"
We put a cheat sheet in the tongue of the boot. At the exam, we specially drop the pen and, bending over it, look at the tongue.

APPOINTMENT OGE

The purpose of the OGE is to assess the level of general education in mathematics for graduates of the ninth grade of general educational organizations for the purpose of state final certification of graduates. The results of the exam can be used when enrolling students in specialized classes secondary school.

STRUCTURE AND CONTENT OF CONTROL AND MEASURING MATERIALS

The work consists of two modules: "Algebra" and "Geometry". Each module has two parts corresponding to testing at the basic and advanced levels.

When testing basic mathematical competence, students must demonstrate mastery of basic algorithms, knowledge and understanding of the key elements of the content ( mathematical concepts, their properties, methods of solving problems, etc.), the ability to use mathematical notation, apply knowledge to solve math problems not reduced to the direct application of the algorithm, as well as to apply mathematical knowledge in the simplest practical situations.

Part 2 of the modules "Algebra" and "Geometry" are aimed at testing knowledge of the material at an advanced level. Their purpose is to differentiate well-performing schoolchildren by levels of training, to identify the most prepared part of graduates, which constitutes a potential contingent of specialized classes. These parts contain tasks of an increased level of complexity from various sections of the mathematics course. All tasks require a record of solutions and an answer. Tasks are arranged in ascending order of difficulty - from relatively simple to complex, requiring fluency in the material and a good level of mathematical culture.

The Algebra module contains 17 tasks: in part 1 - 14 tasks; in parts 2 - 3 tasks.

The module "Geometry" contains 9 tasks: in part 1 - 6 tasks; in parts 2 - 3 tasks.

In total, there are 26 tasks in the work, of which 20 tasks basic level, 4 advanced quests and 2 high-level quests.

ASSESSMENT SYSTEM

To evaluate the results of work performed by graduates, the total score. The maximum number of points for one task of part 1 is equal to one point, for one task of part 2 it is equal to two points. The maximum score for the work as a whole is 32. Of these, for the "Algebra" module - 20 points, for the "Geometry" module - 12 points.

Tasks estimated at 2 points are considered to be completed correctly if the student has chosen the correct solution path, the course of his reasoning is clear from the written record of the solution, and the correct answer is received. In this case, he is given the full score corresponding to this task. If a mistake is made in the decision that is not of a fundamental nature and does not affect the overall correctness of the decision, then the participant is given 1 point.

Compared to the structure of 2017, the module “ Real math". The tasks of this module are divided into modules "Algebra" and "Geometry".

The recommended minimum result of the examination work in mathematics is 8 points, scored in total for completing the tasks of both modules, provided that at least 2 points of them are received in the "Geometry" module.

Translation scales developed by specialists of FGBNU "FIPI" primary points in marks on a five-point scale for conducting the OGE are RECOMMENDATIONAL.

Used in a specific subject Russian Federation the system for translating primary OGE scores into a five-point scale is adopted by the regional ministry.

The scale for recalculating the total score for the performance of the examination paper as a whole into a mark in mathematics:

Total score for the work as a whole Mark on a five-point scale
0-7 "2"
8-14 "3"
15-21 "4"
22-32 "5"

OGE in mathematics in 2017

ADMISSION TO OGE

Students who do not have academic debts and in in full completed the curriculum, having annual marks in all subjects of the curriculum for grade 9 not lower than satisfactory.

Students are admitted to the GIA, provided they receive marks not lower than satisfactory at the intermediate certification.

Students who are currently academic year winners or runners up final stage All-Russian Olympiad schoolchildren, members of the national teams of the Russian Federation that participated in international Olympiads and formed in the manner established by the Ministry of Education and Science of the Russian Federation, are exempted from passing the state final certification in an academic subject corresponding to the profile of the All-Russian Olympiad for schoolchildren, international Olympiad.

MANDATORY AND ELECTIVE EXAMS

State final certification in educational programs basic general education (GIA-9) is carried out in the form of compulsory state exam(OGE) and includes two mandatory exams in the Russian language and mathematics, as well as two more exams at the choice of the student.

The subjects chosen by the student are indicated in the application that he submits to the educational organization before March 1 of the current year.

In 2017, the results obtained at the OGE in two elective subjects will affect the final grade given in the certificate of the main general education(certificate), as well as to obtain a certificate.

When passing the OGE in 2017, the presence of an unsatisfactory result in more than two academic subjects does not allow the graduate to re-participate in exams in these academic subjects in additional deadlines. Participation in the OGE for such graduates is possible no earlier than September 1, 2017.

Re-to passing the OGE in the relevant academic subjects in the current year, by decision of the SEC, students who received unsatisfactory results at the OGE in no more than two academic subjects are allowed.

EXAM MATERIALS

Control measuring materials (CMM) for conducting the OGE are formed using an open bank of tasks and specialized software posted on the FIPI website.

Before the start of the exam, the organizers conduct a briefing, after which the participants are given sheets (forms) for recording answers.

At the direction of the organizers, participants fill in the registration fields of the examination paper.

The organizers check the correctness of filling in the registration fields of the examination paper by the students.

In case of lack of space in the sheets (forms) for answers to tasks with a detailed answer, at the request of the student, the organizers give him an additional sheet (form). At the same time, the organizers record the connection between the numbers of the main and additional sheet (form) in special fields of sheets (forms).

Drafts are given to students as needed. Students can make notes in KIM for the OGE and texts, topics, tasks, tickets for the GVE.

Entries on KIM, texts, topics, assignments, tickets for the GVE and drafts are not processed or checked.

30 minutes and 5 minutes before the end of the exam, the organizers must inform the participants about the imminent completion of the exam and remind them of the need to transfer answers from drafts to sheets (forms).

Examination tasks for the OGE - control measuring materials (KIM) - are subject specialists of the FGBNU FIPI with the appropriate qualifications (methodologists, scientists, teachers educational institutions and teachers of institutions of primary, secondary and higher vocational education). Their task is to develop tasks for CMM options for each year.

OGE in mathematics in 2016

The work consists of three modules: "Algebra", "Geometry", "Real Mathematics". The modules "Algebra" and "Geometry" include two parts, corresponding to the test at the basic and advanced levels, the module "Real Mathematics" - one part, corresponding to the test at the basic level.

When testing basic mathematical competence, students must demonstrate: possession of basic algorithms, knowledge and understanding of the key elements of the content (mathematical concepts, their properties, problem solving techniques, etc.), the ability to use mathematical notation, apply knowledge to solve mathematical problems that are not reducible to direct application of the algorithm, as well as apply mathematical knowledge in the simplest practical situations.

The Algebra module contains 11 tasks: in part 1 - 8 tasks, in part 2 - 3 tasks.

The module "Geometry" contains 8 tasks: in part 1 - 5 tasks, in part 2 - 3 tasks.

The "Real Mathematics" module contains 7 tasks.

There are 26 tasks in total, of which 20 are basic-level tasks (these twenty tasks make up the first part of the work), 4 advanced-level tasks and 2 high-level tasks (these six tasks make up the second part of the work).

Each work of the first part is evaluated with a maximum of one point, and each work of the second part - with a maximum of two points. Thus, the maximum primary score for doing all the work is 20 x 1 + 6 x 2 = 32 points.

The tasks of part 1 of the modules "Algebra", "Geometry" and "Real Mathematics" check the level of development of the Federal State Educational Standards at the basic level.

The allocation of a separate module "Real Mathematics" and a slight increase in the number of practice-oriented tasks emphasize the importance of mastering such mathematical competencies as the ability to apply tasks in practical life and in related areas.

The tasks of Part 2 are tasks of an increased level of complexity, designed to differentiate graduates of the basic school for specialized education in high school.

The tasks of the second part of the "Algebra" module are aimed at testing the knowledge of the formal-operational algebraic apparatus; the ability to solve a complex problem, which includes knowledge from different topics of the algebra course; the ability to mathematically competently and clearly write down the solution, while providing the necessary explanations and justifications; possession of a wide range of techniques and methods of reasoning.

The tasks of part 2 of the "Geometry" module are aimed at testing the ability to solve a planimetric problem using various theoretical knowledge geometry course; the ability to mathematically competently and clearly write down the solution, while providing the necessary explanations and justifications; possession of a wide range of techniques and methods of reasoning. Of the three tasks offered complete solution There is a task to prove a geometric fact.

WORK TIME

235 minutes are allotted to complete the examination paper.

TIPS AND INSTRUCTIONS FOR DOING THE WORK

First complete the tasks of part 1. It is better to start with the module whose tasks cause you less difficulty, then move on to other modules. To save time, skip the task that you can't complete right away and move on to the next one. If you have time left, you can return to the missed tasks.

Perform all necessary calculations and transformations in a draft. Draft entries do not count towards the assessment of the work. If the task contains a drawing, then you can perform the constructions you need directly on it in the text of the work. We recommend that you carefully read the condition and check the received answer.

Answers to tasks 2, 3, 8, 14 are written as one digit, which corresponds to the number of the correct answer. Write this number in the answer field in the text of the work.

For the remaining tasks of Part 1, the answer is the number or sequence of numbers that you need to write in the answer field in the text of the work. If the response received common fraction, convert it to decimal. If you write down an incorrect answer to the tasks of part 1, cross it out and write down a new one next to it.

Write the solutions to the tasks of part 2 and the answers to them on a separate sheet or form. The tasks can be completed in any order, starting with any module. The text of the task does not need to be rewritten, it is only necessary to indicate its number.

ADDITIONAL MATERIALS AND EQUIPMENT

Students are allowed to use reference materials, containing the basic formulas of the mathematics course, and issued along with the work. You are allowed to use a ruler. Calculators are not used in the exam.

ASSESSMENT SYSTEM FOR PERFORMANCE OF INDIVIDUAL TASKS AND WORK IN GENERAL

To evaluate the results of work performed by graduates, a total score is used. As mentioned above, the maximum score for the work as a whole is 32.

Tasks rated 1 point are considered completed correctly if the number of the correct answer is indicated (in tasks with a choice of answers), or the correct answer is entered (in tasks with a short answer), or the objects of two sets are correctly correlated and the corresponding sequence of numbers is written down (in tasks on matching).

If a mistake is made in the decision that is not of a fundamental nature and does not affect the overall correctness of the decision, then the participant is given 1 point.

On mastering the federal component by a graduate educational standard in subject area"Mathematics" testifies to his overcoming the minimum threshold result of the examination work.

The following recommended minimum criterion is established: 8 points scored in the entire work, of which - at least 3 points in the "Algebra" module, at least 2 points in the "Geometry" module and at least 2 points in the "Real Mathematics" module. Only the fulfillment of all the conditions of the minimum criterion gives the graduate the right to receive a positive examination mark on a five-point scale in mathematics or in algebra and geometry (in accordance with the curriculum of the educational organization).

CHANGES IN THE EXAM WORK IN 2016 COMPARED TO 2015

The structure and content of the examination paper have not changed. The grading system for tasks 22, 23, 25, 26 has been adjusted (the maximum score for completing each of them is 2). The maximum primary score for completing the entire job has been reduced from 38 to 32.

What you need to know about the OGE (GIA-9) in mathematics in 2015

CHARACTERISTICS OF THE STRUCTURE AND CONTENT OF THE EXAM WORK.

These parts contain tasks of an increased level of complexity from various sections of the mathematics course. All tasks require a record of solutions and an answer. Assignments are arranged in ascending order of difficulty - from relatively simple to complex, requiring fluency in the course material and a good level of mathematical culture.

The Algebra module contains 11 tasks: in part 1 - 8 tasks, in part 2 - 3 tasks.

The module "Geometry" contains 8 tasks: in part 1 - 5 tasks, in part 2 - 3 tasks.

The "Real Mathematics" module contains 7 tasks.

Total: 26 tasks, of which 20 are basic tasks, 4 are advanced tasks and 2 are high-level tasks.

WORK TIME

235 minutes are allotted to complete the examination paper.

CONDITIONS FOR THE EXAM AND VERIFICATION OF WORKS

Mathematicians are not allowed in the classroom during the exam. The use of a single instruction for conducting an exam makes it possible to ensure compliance with uniform conditions without involving persons with special education in this subject.

Students at the beginning of the exam are given full text work. Answers to the tasks of Part 1 can be recorded directly in the text of the work, and then, in the case of using blank technology, the answers must be transferred to the answer form No. 1. The tasks of Part 2 are performed with a record of the solution and the answer received on separate sheets or on answer forms No. 2 . Task formulations are not rewritten, it is enough to indicate the task number.

Students can make all the necessary calculations, transformations and drawings in a draft. Drafts are not checked.

Examination papers are checked by mathematicians who are members of independent regional or municipal examination boards in mathematics.

What is the upcoming OGE preparing for us?

The OGE has not yet become an established exam, on the contrary, it is undergoing more and more changes. Constant transformation excites parents, teachers and, of course, students. You need to know what to prepare for.

Changes in the OGE-2018:

Marks in subjects that are taken at the OGE affect the certificate.

A single scale for marking is being introduced, the minimum threshold is also common to all.

KIMs are the same for the whole country, options are now being developed not in the regions, but by federal commissions.

Informatics is rented using a computer

Transmission Changes

An oral exam in the Russian language will be introduced (in some regions)

The number of compulsory subjects, according to official data, has not changed, there are two of them - mathematics and Russian. The number of mandatory tests was previously planned to be increased to 6, introducing one subject every two years. Most likely, this will happen soon. According to experts, this will help to achieve a better level intellectual development schoolchildren. Since the students themselves are in no hurry to choose additional disciplines for delivery, they will have to be made mandatory. Official information on how many exams will be taken in grade 9 in 2018 will appear in the fall, which causes alarm among students and parents. History or a foreign language may be introduced as compulsory subjects.

Choose, give up!

If earlier it was necessary to pass only two subjects for the successful completion of nine classes, then this academic year, students are required to additionally choose two disciplines. Officials believe that two disciplines are not enough to form an outlook, so two more are needed, chosen by the student himself. In addition, it is required for admission to educational establishments or in specialized classes. For those who plan to write the exam, this will be a good help in preparing, a sort of "probe" of the exam. For 2018, the list of selective disciplines is as follows:

Geography.

Biology.

Literature.

Foreign language - English, German, French, Spanish.

Social Studies.

Informatics.

Thus, in order to receive a certificate in 2018, it is necessary to have positive marks in all four subjects.

In order to be admitted to the exams, there should not be an “unsatisfactory” mark in any subject.

How does the OGE affect the mark in the certificate?

The grade for the state exam now affects the mark in the certificate. Therefore, you can either increase or decrease your score. But there is something here that can play into your hands. For example, in the academic year you gave up a little slack in the study of the subject, but you prepared perfectly for the exam and passed it with “5” - they will put “excellent” instead of “4” in the certificate for the academic year.

KIMs

Control and measuring materials used to be developed in each region. But starting this year they will be the same for everyone.

IMMs do not show large changes in their structure. Questions with a simple choice from the proposed remain, in contrast to the more serious exam - the Unified State Examination. But questions with a detailed answer, where students must show the ability to formulate an idea, are actively developed and are present in the exam in each discipline. In particular, in the Russian language exam, it is necessary to write both an essay and a presentation, which causes difficulties for many students. Therefore, the training of such skills must be done in advance.

In the structure of KIM in the Russian language, it is planned to introduce an oral part. They are also considering how this can be organized: to record the answer on a dictaphone and subsequently analyze or evaluate it on the spot by the commission.

Trial versions of KIMs of the last year are posted on the FIPI website, and today you should be guided by them. You need to remember about the GIA Open Job Bank - 9 and actively use it.

How to start preparing for the OGE

Tasks. There are 26 tasks in the OGE in mathematics.

1–20 → part 1, short answer tasks. You are required to solve the problem and write down the answer in the appropriate field on the form; you do not need to give a solution method. In three tasks, the answer is the number of the correct option, and in the remaining seventeen - the number or sequence of numbers.

21–26 → part 2, tasks with a detailed answer. Here it is necessary not only to give an answer, but also to paint the whole course of reasoning.

Course sections. At the OGE in mathematics, knowledge of algebra and geometry is tested for grades 7–9. Each section corresponds to a certain number of tasks with a short answer.

Algebra

Numbers and calculations (3 tasks)

Algebraic expressions (3 tasks)

Equations and inequalities (2 tasks)

Number sequences (1 task)

Functions and graphs (2 tasks)

Statistics and probability theory (3 tasks)

Geometry

Geometric shapes and their properties (1 task)

Triangle (1 task)

Polygons (1 task)

Circle and circle (1 task)

Measurement of geometric quantities (2 tasks)

Time. The exam lasts 3 hours 55 minutes. To solve problems from the first part, which are easier, you need to allocate about 1.5 hours. The rest of the time will be spent solving problems from the second part and recording them in detail.

What you need to know

Make calculations
Perform transformations of algebraic expressions
Solve equations, inequalities and their systems
Build and read graphs
Perform actions with geometric shapes, coordinates and vectors
Describe real situations in the language of geometry
Reasoning logically, giving evidence and finding incorrect conclusions
Solve algebraic and geometric problems using knowledge from different sections of the course
Mathematically competently and reasonably write down the solution in tasks with a detailed answer

How is work evaluated?

1 point → tasks 1–20

2 points → tasks 21–26

To get 2 points for the task from the second part, you must:

1. Correctly solve the problem

2. Write down the solution so that the course of your reasoning is clear to the examiners

3. Get the right answer

If there are inaccuracies or small errors in the solution, but it is essentially correct, then you will get 1 point.

The maximum you can get at the OGE in mathematics is 32 points. They are translated into an assessment on a five-point scale.

The number of points that corresponds to the marks "excellent" and "good" is not known in advance. It is determined by the results of passing the exam by all students. Therefore, do not strive to calculate the minimum passing score, but try to correctly complete the maximum number of tasks.

1. Be confident and take your time

Lots of mistakes in examination papers allowed due to haste or inattention.

Task example

You need to check all the statements, but choose the one that wrong. Very often, students find the correct statement, mark its number in the answer and rush to the next problem. As a result, they lose points at the easiest stage.

Answer: statement 1 is false in this case.

2. Read the terms carefully

In some problems, the condition is formulated in such a way that it is easy to get confused. Pay attention to all the nuances - if necessary, write down the condition point by point.

Task example

The key words here are "on the first day of each following week." At the same time, the price does not decrease every day of the second week, but only once, on the first day. In addition, it is important not to make a mistake with the number of days in a week and correctly determine the moment when the price starts to decline. The correctness of the answer also depends on this.

Answer: 800 rubles, since on the eighth day the price decreased by 20% from 1000 rubles and remained so throughout the second week, that is, from the eighth to the fourteenth day. The twelfth day specified in the condition is included in this interval.

3. Learn formulas

Using a formula, you can solve a problem much faster than by adding or selecting options.

Task example

Instead of adding the values of the first six terms of the progression, you can find the answer using the formula:

The denominator of the progression is the ratio of its neighbors. Do not confuse this concept with the denominator of a fraction.

Answer. By the condition of the problem q=2. We substitute this value into the formula and get the answer: - 47.25.

If, when solving a problem with a detailed answer, you use a formula that is not in school curriculum, Be sure to provide proof. Otherwise, you may not receive one point.

4. Always choose the easiest and fastest solution

This is especially true for questions with a short answer. The faster you solve them, the more time you will have to complete the second part of the work.

Task example

Here you do not need to substitute values in the inequality and check its correctness. It is enough to understand how the graph of the function looks like from the condition, and correlate it with the given figures.

x 2 - 6x - 27 is the parabola f(x)=ax 2 +bx+c.

a>0, so the branches of the parabola are directed upwards.

from<0, значение в нуле отрицательно, поэтому вершина параболы, в которой принимается минимальное значение, тоже лежит ниже оси Ox.

If the value of the equation describing the graph of the parabola is less than zero, then we are interested in that part of the graph that is below the Ox axis. It corresponds to a certain range of x values between the roots of the trinomial, that is, a segment. Only Figure 4 meets this condition, it shows a segment with ends at points - 3 and 9.

Answer: 4.

5. When solving geometric problems, always draw

This also applies to the tasks of the first part, where you do not need to paint the solution. First of all, you need a drawing to understand the condition of the problem, write everything correctly and find the right answer. Without a picture, the likelihood of making a mistake increases.

Task example

Figure for solution

6. Solve as many geometry problems as possible

Geometric problems usually cause more difficulties than algebraic ones. To overcome your fear of “that terrible geometry” and learn how to cope with a wide variety of problems, you need to solve as many of them as possible.

It is unlikely that there will be a final exam more difficult than the OGE or the USE in chemistry. This subject has to be taken by future biologists, chemists, physicians, engineers and builders. Today we will talk about what you need to know in order to get high scores, and what benefits are best to use.

Books and manuals for preparation

Experts of the Unified State Examination and the OGE recommend that, when preparing, rely on textbooks of a specialized level. The material of the standard basic textbook is not enough to successfully pass the exam. Practice shows that schoolchildren who have taken a profile course in chemistry feel quite confident during the exam. There are several such textbooks, but they are approximately the same in content and presentation.

We recommend that you get a collection of typical examination tasks - the official publication of FIPI (with a hologram) and a couple of books by other authors. They analyze tasks in detail, show ways to solve them, give algorithms and answers for self-control. The more options you solve, the greater your chances of successfully passing the exam.

Repetition is the mother of learning

This is an important part of quality training. Chemistry is a complex science of matter, without knowing the elementary topics of the initial course, you will not understand the more complex ones. Of course, there may not be enough time to repeat the entire program, so it is better to pay more attention to precisely those issues that cause the most difficulties.

According to the teachers of the Merlin Center, students are more likely to make mistakes in tasks related to the following topics:

mechanisms of formation of molecular bonds;
hydrogen bond;
patterns of chemical reactions;
physico-chemical properties of solutions, electrolytic dissociation, reactions in electrolyte solutions;
the effect of solution dilution on the degree of dissociation (Ostwald's dilution law);
salt hydrolysis;
atmospheric compounds;
main classes of compounds;
industrial production and scope.

The same standard examination tasks and tests will help to identify gaps. Does not work? Ask a chemistry teacher for help or sign up for prep courses.

Put experiments

Chemistry is a science built on real experiments with substances. Experiments will help to better understand a particular topic. To do this, it is not necessary to buy a set of reagents and laboratory supplies. There are many interesting, well-filmed videos on the Internet about chemical reactions. Feel free to find them and see.

Be careful on the exam!

Most mistakes are made by the guys precisely because of inattention. Train yourself not to skip a single word while reading the task, pay attention to the wording and how many answers should be.

Read the question to the end, think about its meaning. There is often a little clue hidden in the wording.
Start with easy questions where you have no doubt about the correctness of the answers, then move on to more difficult tasks where you need to think.
If a question is too difficult, skip it, do not waste time, you can return to it later.
Tasks are not related to each other, so focus only on the one you are doing at the moment.
If you find it difficult, first try to exclude clearly incorrect answers. It is easier to choose an option from the remaining two or three than to get confused in five or six answers.
Be sure to leave time to check your work so that you can quickly review the assignments and correct any mistakes. An unfinished word or number can cost you a point.

Chemistry is a difficult subject, and it is best to prepare for the exam under the guidance of an experienced teacher; it is not recommended to count on the fact that you will cope with such a responsible task. Only a teacher can point out "imperceptible" mistakes and help you fill in the gaps, explain complex material in a simple, accessible language.
