Changes in KIM USE 2018 in chemistry of the year compared to 2017
The following changes have been made in the 2018 examination paper compared to the 2017 paper.
1. In order to more clearly distribute the tasks for separate thematic blocks and content lines, the order of the tasks of the basic and advanced levels of complexity in part 1 of the examination paper has been slightly changed.
2. In the examination paper of 2018, the total number of tasks was increased from 34 (in 2017) to 35 by increasing the number of tasks of part 2 of the examination paper from 5 (in 2017) to 6 tasks. This is achieved by introducing tasks with a single context. In particular, tasks No. 30 and No. 31 are presented in this format, which are focused on checking the assimilation of important elements of the content: “Redox reactions” and “Ion exchange reactions”.
3. The grading scale for some tasks has been changed in connection with the clarification of the difficulty level of these tasks based on the results of their completion in the 2017 examination paper:
Task No. 9 of an increased level of complexity, focused on checking the assimilation of the content element “Characteristic chemical properties of inorganic substances” and presented in a format to establish a correspondence between reacting substances and reaction products between these substances, will be evaluated with a maximum of 2 points;
Task No. 21 of the basic level of complexity, focused on checking the assimilation of the element of the content "Redox reactions" and presented in the format to establish a correspondence between the elements of two sets, will be assessed by 1 point;
Task No. 26 of the basic level of complexity, focused on checking the assimilation of the content lines "Experimental Fundamentals of Chemistry" and "General Ideas about Industrial Methods for Obtaining the Most Important Substances" and presented in a format to establish a correspondence between the elements of two sets, will be assessed with 1 point;
Task No. 30 of a high level of complexity with a detailed answer, focused on checking the assimilation of the content element “Redox reactions”, will be evaluated with a maximum of 2 points;
Task No. 31 of a high level of complexity with a detailed answer, focused on checking the assimilation of the content element "Ion exchange reactions", will be evaluated with a maximum of 2 points.
In general, the adopted changes in the examination work in 2018 are aimed at increasing the objectivity of testing the formation of a number of important general educational skills, primarily such as: apply knowledge in the system, independently assess the correctness of the implementation of educational and educational and practical tasks, as well as combine knowledge about chemical objects with an understanding of the mathematical relationship between various physical quantities.
Structure of KIM USE 2018 in chemistry
Each version of the examination work is built according to a single plan: the work consists of two parts, including 35 tasks.
Part 1 contains 29 tasks with a short answer, including 21 tasks of a basic level of complexity (in the version they are present under numbers: 1–7, 10–15, 18–21, 26–29) and 8 tasks of an increased level of complexity (their ordinal numbers: 8, 9, 16, 17, 22–25).
Part 2 contains 6 tasks of a high level of complexity, with a detailed answer. These are tasks numbered 30-35.
Specification
control measuring materials
for holding the unified state exam in 2018
in chemistry
1. Appointment of KIM USE
The Unified State Examination (hereinafter referred to as the USE) is a form of objective assessment of the quality of training of persons who have mastered the educational programs of secondary general education, using tasks in a standardized form (control measuring materials).
The USE is conducted in accordance with Federal Law No. 273-FZ of December 29, 2012 “On Education in the Russian Federation”.
Control measuring materials allow to establish the level of development by graduates of the Federal component of the state standard of secondary (complete) general education in chemistry, basic and profile levels.
The results of the unified state exam in chemistry are recognized by educational institutions of secondary vocational education and educational institutions of higher professional education as the results of entrance examinations in chemistry.
2. Documents defining the content of KIM USE
3. Approaches to the selection of content, the development of the structure of the KIM USE
The basis of approaches to the development of KIM USE 2018 in chemistry was those general methodological guidelines that were determined during the formation of examination models of previous years. The essence of these settings is as follows.
- KIM are focused on testing the assimilation of the knowledge system, which is considered as an invariant core of the content of existing programs in chemistry for general education organizations. In the standard, this system of knowledge is presented in the form of requirements for the preparation of graduates. These requirements correspond to the level of presentation in the KIM of the content elements being checked.
- In order to ensure the possibility of a differentiated assessment of the educational achievements of graduates of the KIM USE, they check the development of basic educational programs in chemistry at three levels of complexity: basic, advanced and high. The educational material on the basis of which tasks are built is selected on the basis of its significance for the general educational preparation of secondary school graduates.
- The fulfillment of the tasks of the examination work involves the implementation of a certain set of actions. Among them, the most indicative are, for example, such as: to identify the classification features of substances and reactions; determine the degree of oxidation of chemical elements according to the formulas of their compounds; explain the essence of a particular process, the relationship of the composition, structure and properties of substances. The ability of the examinee to carry out various actions when performing work is considered as an indicator of the assimilation of the studied material with the necessary depth of understanding.
- The equivalence of all variants of the examination work is ensured by maintaining the same ratio of the number of tasks that test the assimilation of the main elements of the content of the key sections of the chemistry course.
4. The structure of KIM USE
Each version of the examination work is built according to a single plan: the work consists of two parts, including 40 tasks. Part 1 contains 35 tasks with a short answer, including 26 tasks of a basic level of complexity (the serial numbers of these tasks: 1, 2, 3, 4, ... 26) and 9 tasks of an increased level of complexity (the serial numbers of these tasks: 27, 28, 29, ...35).
Part 2 contains 5 tasks of a high level of complexity, with a detailed answer (the serial numbers of these tasks: 36, 37, 38, 39, 40).
The result of the Unified State Examination in Chemistry not lower than the minimum set number of points gives the right to enter universities for specialties where the list of entrance examinations includes the subject of chemistry.
Universities do not have the right to set a minimum threshold for chemistry below 36 points. Prestigious universities tend to set their minimum threshold much higher. Because in order to study there, first-year students must have very good knowledge.
On the official website of the FIPI, versions of the Unified State Examination in Chemistry are published every year: demonstration, early period. It is these options that give an idea of the structure of the future exam and the level of complexity of tasks and are sources of reliable information in preparing for the exam.

There are changes in the USE options in chemistry in 2017 compared to the KIM of the last 2016, so it is advisable to train according to the current version, and use the options from previous years for the diverse development of graduates.
Additional materials and equipment
The following materials are attached to each version of the USE examination paper in chemistry:
− periodic system of chemical elements D.I. Mendeleev;
− table of solubility of salts, acids and bases in water;
− electrochemical series of voltages of metals.
It is allowed to use a non-programmable calculator during the examination work. The list of additional devices and materials, the use of which is allowed for the Unified State Examination, is approved by the order of the Ministry of Education and Science of Russia.
For those who want to continue their education at a university, the choice of subjects should depend on the list of entrance tests in the chosen specialty
(direction of training).
The list of entrance examinations in universities for all specialties (training areas) is determined by the order of the Russian Ministry of Education and Science. Each university chooses from this list those or other subjects that are indicated in its admission rules. You need to familiarize yourself with this information on the websites of selected universities before applying for participation in the Unified State Examination with a list of selected subjects.
Demonstration versions of the exam in chemistry for grade 11 for 2002 - 2014 consisted of three parts. The first part included tasks in which you need to choose one of the proposed answers. The tasks from the second part were required to give a short answer. To the tasks from the third part it was necessary to give a detailed answer.
In 2014 in demonstration version of the exam in chemistry the following changes:
- all calculation tasks, the performance of which was estimated at 1 point, were placed in part 1 of the work (A26-A28),
- subject "Redox Reactions" tested with assignments AT 2 And C1;
- subject "Hydrolysis of salts" checked only with the task AT 4;
- a new task has been included(in position AT 6) to check the topics "qualitative reactions to inorganic substances and ions", "qualitative reactions of organic compounds"
- total number of jobs in each variant was 42 (instead of 43 in the work of 2013).
In 2015 in demo in chemistry were made fundamental changes:
- The grading system has been changed. tasks for finding the molecular formula of a substance. The maximum score for its implementation - 4 (instead of 3 points in 2014).
Option became be in two parts(part 1 - short answer questions, part 2 - open-ended questions).
Numbering assignments has become through throughout the variant without letter designations A, B, C.
Was the form of recording the answer in tasks with a choice of answers has been changed: the answer has become necessary to write down the number with the number of the correct answer (and not mark with a cross).
Was the number of tasks of the basic level of complexity has been reduced from 28 to 26 tasks.
Maximum score for completing all the tasks of the examination paper in 2015 became 64 (instead of 65 points in 2014).
IN 2016 year in demo version in chemistry made significant changes compared to the previous year 2015:
Part 1 changed the format of tasks 6, 11, 18, 24, 25 and 26 basic level of difficulty with a short answer.
Changed the format of tasks 34 and 35 increased level of complexity : these tasks now require you to match instead of selecting multiple correct answers from a suggested list.
The distribution of tasks by difficulty level and types of skills being tested has been changed.
In 2017, in comparison with the demonstration version of 2016, in chemistry there were significant changes. The structure of the examination paper has been optimized:
Was changed the structure of the first part demo version: tasks with a choice of one answer were excluded from it; tasks were grouped into separate thematic blocks, each of which began to contain tasks of both basic and advanced levels of complexity.
Was reduced the total number of tasks up to 34.
Was grading scale changed(from 1 to 2 points) completing tasks of the basic level of complexity, which test the assimilation of knowledge about the genetic relationship of inorganic and organic substances (9 and 17).
Maximum score for the completion of all tasks of the examination paper was reduced to 60 points.
In 2018 in demo version of the exam in chemistry Compared to the 2017 demo in Chemistry, the following changes:
Was task 30 added high level of complexity with a detailed answer,
Maximum score for the completion of all tasks of the examination work remained without change by changing the scale for grading tasks in part 1.
IN demonstration versions of the Unified State Exam 2019 - 2020 in chemistry compared to the 2018 chemistry demo there were no changes.
The exam in chemistry in 2018 will undergo some changes. Some of them are significant. They will be discussed in this article. In particular, it will talk about how the structure of the exam is changing and what is new in it.
Changes and their meaning
The USE in Chemistry 2018 is taken by both students in the 11th grade and graduates of colleges and technical schools who want to continue their studies at the university, which means that preparation for the USE in chemistry must be done carefully.
The main changes in the exam in chemistry are associated with the absence of a part with a choice of answers. Now even the simplest tasks require a short written answer. This eliminates the possibility of guessing the answer and motivates to prepare tests more efficiently.
The USE news informs that the total number of USE tasks in chemistry has increased to 35 due to the addition of the sixth to the second part. Introduced tasks with a common context. For example, in this form, No. 30 and No. 31 are presented. Here, the assimilation of material on the topic "Redox reactions" and "ion exchange reactions" is checked.
Depending on the level of difficulty, the grading scale undergoes changes. Next, we will analyze how exactly the scale has changed in some tasks.
Estimating some tasks
Task number 9, which has an increased level of complexity, focuses on testing knowledge on a topic related to the chemical properties of inorganic substances. It is necessary to establish a correspondence between the substances and products of the resulting reaction. The maximum score for it is 2 points. In the basic level No. 21, knowledge on the topic of redox reactions is tested. It is necessary to establish a correspondence between the components of the two sets. Correct execution will bring the examiner 1 point
Foundation Level 26 tests the student on topics such as the experimental foundations of chemistry and understanding of the most important substances produced by industrial methods. The task score is also 1 point.
Nos. 30 and 31 are classified as a high level of difficulty. Each of them is estimated at 2 points, aimed at knowing the reactions in substances.
Tasks of the 2nd part involve a detailed answer and checking from 2 to 5 elements. Depending on the number of required elements, the score for each task varies from 2 to 5 points. Let's list the tasks of this part:
Added new tasks 9 and 31, simplified 10, which is the twenty-first in the exam in chemistry in 2018.
All changes are aimed at improving the student's knowledge and testing procedures and his ability to navigate chemistry. The primary score is maximum 60, for universities it is recalculated according to the 100-point mark.
How will the exam take place?
The examinee is given 210 minutes to complete the entire work of the USE 2018 in chemistry. Each task is assigned a specific time:
- Basic level of difficulty - performed within 1-3 minutes;
- Up to 7 minutes can be spent on an increased level of difficulty;
- The last tasks of a high level of difficulty 2 parts are completed up to 15 minutes.
Each version of the examination paper is stored in KIMs and is opened only in the presence of students. In addition to the tasks themselves, an additional table of chemical elements, the solubility of substances in water, as well as electrochemical stresses in metals is issued. It is allowed to use a non-programmable calculator. Drafts are issued only at the request of the student.
Exam Demo
A demo version of the exam in chemistry has already appeared on the official fipi portal. It is approximately similar to those that will be on the official exam. Each task is written in detail, indicating the number of points. At the end, the correct answers are given and it is written, for which the maximum number of points is given. The demo version of the exam in chemistry will be useful to everyone who is going to take this exam, especially when entering the chemical and medical faculties, as well as building institutes for architecture.
