The number of tasks has decreased to 34. It is known that the minimum score remained the same - 36. The maximum primary score has decreased to 60. Points are awarded for correctly or partially correctly completed tasks.

New demo 2017 in chemistry from FIPI.

The structure of the examination work has been optimized:

In the exam paper 201734 tasks, which are divided into two unequal blocks. The first part contains 29 tasks, and the second - 5.

1. The structure of part 1 of the CMM has been fundamentally changed: tasks with a choice of one answer are excluded; tasks are grouped into separate thematic blocks, each of which has tasks of both basic and increased difficulty levels.

2. The total number of tasks has been reduced from 40 (in 2016) to 34.

3. Changed the assessment scale (from 1 to 2 points) for the tasks of the basic level of complexity, which check the assimilation of knowledge about the genetic relationship of inorganic and organic substances (9 and 17).

4. The maximum primary score for the performance of the work as a whole will be 60 points (instead of 64 points in 2016). Physics - significant changes The structure of part 1 of the examination paper has been changed, part 2 is left unchanged.

Afterword

After familiarizing yourself with the general information about the exam, proceed immediately to

preparation. This year's exam is completelyis not different from previous years, so you can prepare based on materials from both 2015 and 2016.

How many points are given for each task of the exam in chemistry. Criteria for evaluating the exam in chemistry 2020: points and grades, a translation table, as well as the structure of the exam, the test methodology and the main changes in the new year. In 2020, tasks for the exam in chemistry began to contain more mathematical elements, calculations of physical quantities, and the verification of the main theoretical course of chemistry became deeper. At the same time, the number of tasks has decreased, now instead of 40 questions, the student will have to solve 35 (according to other sources, 34). Accordingly, the assessment scale has changed, for the USE in chemistry in 2020 the primary score has become lower - by 4 units.

All tasks are evaluated in different ways, for difficult tasks you can earn up to 5 points. Therefore, for admission to specialized universities, it is necessary to study the subject as deeply as possible.

Table of criteria for evaluating the tasks of the exam 2020 in chemistry, taking into account the new requirements:

Assessment of assignments is carried out according to the established methodology, while for complex assignments where logic is required, points are set using special analytical tables. If the answer meets the requirements of the analysis as much as possible, you can get up to 5 points for it. If the student has developed the topic only partially, then the number of points is reduced. For an uncompleted task, 0 points are awarded.

Difficult assignments are checked by two experts. If there is a strong discrepancy in points, then a third specialist is involved. This ensures the most effective and objective assessment of the knowledge of graduates.

Conversion table for the USE-2020 in chemistry from points to grades:

Number of points

Grade

The structure of the USE assignments in chemistry in 2020 includes 29 questions with a short answer, as well as 5 with a detailed one.

The exam lasts 210 minutes, according to the standard, simple questions should take about 3 minutes, difficult ones - up to 15. As for the minimum score for passing to specialized universities, each higher educational institution sets its own requirements. For example, for admission to the Faculty of Chemistry of Moscow State University, or the prestigious Moscow Medical University, you must score at least 50 points.

But usually the total passing score in prestigious universities is 400-470 (at least less for the chemistry department, more for the medical department), and admission to the same Moscow State University does not depend on chemistry alone, so if there are not enough points, you can get it in mathematics, biology, Russian and internal entrance examinations.

Significant changes in the USE are also observed in other subjects.

To successfully pass chemistry, it is recommended that you devote most of your time to solving problems and the equation. During delivery, you can use a calculator, periodic table and salt solubility. The electrochemical series of metal voltages is also permitted.

The criteria for assessing the USE in chemistry 2020 are described quite clearly in the regulations, but each graduate has the right to appeal.

Table of transfers of points in the assessments of the OGE-2020 in chemistry

Graduates of the 9th grade have their own assessment criteria. According to all KIM and GIA, a maximum of 34 points can be scored. But if a graduate wants to go to a medical college, a specialized class or some other secondary special education related to chemistry, pharmacy and medicine, he needs to score 23 points or more.

Table of transfers of points in chemistry for the OGE-2020


Despite the seeming simplicity, it is not so easy to get 9 points for the minimum passing grade. You need to be able to solve problems, navigate formulas, at least have a minimal knowledge of theory. Those who pass for a deuce will stay for the second year if they fail the retake too.

Score table for assignments:


Job number

2 (1 - if partially solved)

2 (1 - if partially solved)

2 (1 - if true by 2/3)

2 (1 - if true by 2/3)

Many schoolchildren, in order to play it safe, begin to solve immediately with difficult tasks. If you solve them all without mistakes, you can get 19 points at once, that is, for the "four". However, this implies a complete solution to the task, otherwise it will be estimated at 1 point, or even not at all.

The criteria for assessing testing in chemistry change every year, the rules become stricter, as there is an idea among the government about insufficient quality education. This, of course, is unfounded, because schoolchildren do worse not because of the program, but mostly because of overload.

What will go to the certificate? What if the exam in chemistry is written with a two?

If the exam in chemistry is not passed, and in mathematics and Russian there are normal grades, the student will simply be given a certificate. And they will also give a USE certificate, where chemistry simply will not be entered. In this case, the exam can be retaken in a year. There is only one minus here - the total score for admission may not be enough, and if the university requires chemistry without fail, then documents will not be accepted at all. Accordingly, the student is wasting time, and young men may even be taken into the army, after which it will be even more difficult to retake.

If a grade is 4 or 5 for a year, and the USE in chemistry is passed at 3 or 4 (that is, a decrease in the score), what will go to the certificate? The annual mark will go. If the exam is passed for 5, and for a year 3, then it also does not affect the certificate. But each specific school, where they were obliged to count the arithmetic mean.

Why it happens? Because no one later checks this calculation. Based on this, it is better to decide the issue in advance with a chemistry teacher and class teacher, usually in normal schools, teachers try to meet graduates halfway. If a child has 4, but he pushed and passed the exam for 5, why not help him?

But! It must be remembered that no one needs marks in the certificate upon admission, and especially in chemistry. They look today in 99% of cases only at the USE certificate. Tags:

Already on March 16, the early period for the USE-2017 in chemistry starts. This optional subject cannot compete with history and social studies in terms of popularity. However, for admission to some higher institutions that are related to medicine, biotechnology and the oil industry, one cannot do without chemistry. Therefore, for a small contingent of high school students and applicants, the Unified State Exam in this subject will always be relevant. It is to them that our review is devoted, highlighting the main aspects of the future state testing in chemistry.

the date of the

First, let's figure out when it is worth waiting for the start of the state exam. In 2017, exams will take place between March and June.

  • Early round - March 16.
  • The main stage is June 2.
  • Reserve - April 3, June 19 and 30.

Changes in the exam in chemistry 2017

Testing material has changed significantly. The emphasis in the new KIMs is placed on the examinee's ability to navigate well in all aspects of the school chemistry course.

  1. The number of tasks has decreased: 34 instead of the previous 40.
  2. The first part of the verification work has been modified. Some of the questions are grouped into separate thematic blocks, and matching tasks have appeared.
  3. The maximum primary score has been reduced to 60 (was 64).

Testing material structure

To understand what the new CMM looks like now, let's turn to the demo version of the USE in chemistry 2017.

The subjects will have to puzzle over 34 tasks, which are divided into two unequal blocks. The first part contains 29 tasks, and the second - 5.

First block consists of basic level questions. Basically, these are matching assignments. For example, question # 5 has two columns. One consists of a list of formulas:

  • A. NH4HCO3;
  • B. KF;
  • B. NO.

Second it is also a list of classes / groups of chemical elements:

  • medium salt;
  • acidic oxide;
  • non-salt-forming oxide;
  • acidic salt.

The examinee will be required to determine which group or class corresponds to a particular formula. For the second block of examination questions in chemistry 2017, FIPI prepared complicated tasks. They require not only an answer, but also a detailed description of the solution. These are questions # 30 - 34.

The exam lasts exactly 210 minutes. You can use a calculator during the test. In addition, CMM has a periodic table, as well as a table of the solubility of salts / acids / bases in water and an electrochemical series of metal voltages.

Correct answers are recorded in a special examination form.

Evaluation Criteria for the Unified State Exam in Chemistry 2017

The number of assignments decreased, which introduced some confusion in the grading system. However, it is already known that the minimum score has remained the same - 36. The maximum primary score has decreased to 60. Points are awarded for correctly or partially correctly completed tasks.

  • 1 point: questions 1 - 8, 12 - 16, 20 - 21, 27 - 29.
  • 2 points: 9 – 11, 17 – 19, 22 – 26.
  • 3 points: 30.
  • 4 points: 31, 33 and 34.
  • 5 points: 32.

These points can only be earned for answers that fully meet all the criteria.

Afterword

So, we have sorted out the main aspects of the upcoming testing in chemistry. Now you know the exact date of the state exam, the structure of the KIM and the latest changes related to this subject. Moreover, the list of educational web portals and training materials presented to your attention will help you start preparing for the exam right now. Moreover, most of the materials from the sites dedicated to the exam in chemistry can be downloaded for free. So self-study will not cost you a pretty penny!

To pass the final exams at school. It will need to be passed for admission to universities in the following areas: chemistry and chemical technology, medicine, construction, biotechnology and others. Against the general background, the exam is not very popular - only one student out of ten graduates chooses chemistry.

Read the general information about the exam and start preparing. The version of the KIM USE 2019 has some differences from last year: 1) a task of a high level of difficulty with a detailed answer was added to part 2, 2) the difficulty level and the maximum primary score were revised on four questions (the maximum score did not change throughout the test), 3) for For a clearer distribution of tasks by thematic blocks, the developers slightly changed their order in part 1.

Assessment of the exam

Last year, in order to pass the USE in chemistry at least for the top three, it was enough to score 37 primary points. They were given, for example, for correctly completing the first 15 items of the test.

It is not yet known exactly how it will be in 2019: we need to wait for an official order from Rosobrnadzor on the correspondence of the primary and test scores. Most likely it will appear in December. Given that the maximum primary score for the entire test remains the same, most likely the minimum score will not change either. We focus on these tables so far:

The structure of the exam test

In 2019, the test consists of two parts, including 35 tasks.

  • Part 1: 29 tasks (1–29) with a short answer (a number or a sequence of numbers);
  • Part 2: 6 tasks (30–36) with a detailed answer, the complete solution of the tasks is recorded on the answer form 2.

Preparation for the exam

  • Take the exam tests online for free without registration and SMS. The presented tests are identical in complexity and structure to real exams conducted in the corresponding years.
  • Download the demo versions of the exam in chemistry, which will help you better prepare for the exam and take it easier. All proposed tests are developed and approved for preparation for the exam by the Federal Institute for Pedagogical Measurements (FIPI). In the same FIPI, all the official versions of the Unified State Exam are being developed.
    The tasks that you will see, most likely, will not be encountered on the exam, but will be similar to the demo ones, on the same topic or simply with different numbers.
  • Become familiar with basic exam preparation formulas to refresh your memory before trying the demo and test options.

The maximum number of points that an examinee can receive for completing the entire examination work (with a real experiment) is 38 points.

The system for assessing the performance of individual tasks and the examination work of the OGE 2018 in chemistry as a whole.

Students' answers to the tasks of Part 1 are checked by experts or using a computer. Correct performance of each of tasks 1–15 is estimated with 1 point. Correct completion of each of the tasks 16-19 is estimated at a maximum of 2 points.

Tasks 16 and 17 are considered completed correctly if in each of them two answers are correctly chosen. For an incomplete answer - one of two answers is correctly named or three answers are named, of which two are correct - 1 point is given. The rest of the answers are considered incorrect and are scored 0 points.

Tasks 18 and 19 are considered completed correctly if three matches are correctly established. The answer is considered to be partially correct, in which two matches out of three are established; it is estimated at 1 point. The rest of the options are considered an incorrect answer and are scored 0 points.

Checking the tasks of part 2 (20-23) is carried out by the subject commission. When evaluating each of the three tasks, the expert, on the basis of comparing the graduate's answer with the sample answer given in the assessment criteria, identifies elements in the student's answer, each of which is evaluated by 1 point. Maximum mark for a correctly completed task: for tasks 20 and 21 - 3 points each; in model 1 for task 22 - 5 points; in model 2 for task 22 - 4 points, for task 23 - 5 points.

Tasks with a detailed answer can be completed by students in different ways. Therefore, the sample decisions given in the evaluation criteria should be considered only as one of the possible answers. This applies, first of all, to the methods of solving computational problems.
