How is the first part of the exam in physics assessed?

In some tasks, there are several correct solutions, which is why different interpretations of the correct completion of the task are possible. Don't be afraid to appeal if you think your score was calculated incorrectly.

Check out general information about the exam and start preparing. Compared to last year, the KIM Unified State Exam 2019 has changed somewhat.

Unified State Examination

Last year, to pass the Unified State Exam in Physics with at least a C, it was enough to score 36 primary points. They were given, for example, for correctly completing the first 10 tasks of the test.

It is not yet known exactly what will happen in 2019: we need to wait for the official order from Rosobrnadzor on the correspondence of the primary and test scores. Most likely it will appear in December. Considering that the maximum primary score has increased from 50 to 52, it is very likely that the minimum score may change slightly.

In the meantime, you can focus on these tables:

Structure of the Unified State Exam

In 2019, the Unified State Examination test in physics consists of two parts. Task No. 24 on knowledge of astrophysics was added to the first part. Because of this total number The number of tasks in the test increased to 32.

• Part 1: 24 tasks (1–24) with a short answer that is a number (integer or decimal) or a sequence of numbers.
• Part 2: 7 tasks (25–32) with a detailed answer, in them you need to describe in detail the entire progress of the task.

Preparation for the Unified State Exam

• Take the Unified State Exam tests online for free without registration or SMS. The tests presented are identical in complexity and structure to the actual exams conducted in the corresponding years.

• Download demo versions of the Unified State Examination in Physics, which will allow you to better prepare for the exam and pass it easier. All proposed tests have been developed and approved for preparation for the Unified State Exam by the Federal Institute of Pedagogical Measurements (FIPI). In the same FIPI all official Unified State Exam options.
  The tasks that you will see most likely will not appear on the exam, but there will be tasks similar to the demo ones, on the same topic or simply with different numbers.
• Familiarize yourself with the basic exam prep formulas to help refresh your memory before attempting the demos and test options.

Rejoice, those taking the Unified State Exam in Physics in 2019! On the official website of FIPI along with specifications and codifiers. There are changes in some subjects that the developers of the Unified State Exam KIMs say are unprincipled. But this did not affect physics. So you can start or continue preparing for your chosen exam using old tests and textbooks, using demo versions as a model.

Features of the Unified State Exam in Physics

The Unified State Exam in Physics is an optional exam. It is optional. It is chosen by children who need this subject for admission to universities for all engineering and technical specialties. Approximately 30% of all graduates pass this exam.

Physics is now very popular, everyone’s attention is focused on it. Russia has a special strategy for the development of this area, so the country needs more good engineers.

The average score in physics among those entering technical universities is growing from year to year. This suggests that school graduates approach their preparation very responsibly.

Distribution of points on a 100-point scale in the Unified State Examination in Physics:

To successfully pass, you must complete 32 tasks.

The duration of the exam is 3 hours 55 minutes.

Physics is a special subject. Some things need to be crammed, and some things need to be understood.

So, you need to learn the laws of physics in order to know the formulation, concepts, formulas. But then the student must learn to see these formulas in assignments, examples, and in life.

General changes to the Unified State Exam in 2019

KIM has introduced additional reminder instructions for graduates in all subjects.

The point is that it is necessary to check the records of answers on forms No. 1 and No. 2 under the corresponding task numbers.

There are no changes in the testing materials and assessment criteria in the Unified State Examination in Physics!

Changes in the Unified State Exam in Physics 2018

Please note that in 2018, changes were made to the Unified State Exam in Physics. In general, the structure of control measuring materials was retained, but a task was added on astronomical material, which was studied in the physics course.

In section 5 “Quantum physics and elements of astrophysics” of the codifier, the topic “Elements of Astrophysics” has been added with the following content elements:

1. Solar system: terrestrial planets and giant planets, small bodies solar system.
2. Stars: variety of stellar characteristics and their patterns. Sources of star energy.
3. Modern ideas about the origin and evolution of the Sun and stars.
4. Our Galaxy. Other galaxies. Spatial scales of the observable Universe.
5. Modern views on the structure and evolution of the Universe

In addition, in paragraph 1.2.7 of the “Mechanics” section, which is devoted to the movement of celestial bodies and their artificial satellites, in addition to the first escape velocity, a formula for the second escape velocity is included.

Let us dwell in more detail on what knowledge is required to complete exam tasks for each of these points:

• p. 5.4.1: know the structure of the Solar system, the main differences between the terrestrial planets and the giant planets and distinctive features each of the planets, understand the reasons for the change of day and night and the change of seasons, be able to calculate the first and second cosmic velocities;
• p. 5.4.2: distinguish between the spectral classes of stars, understand the relationship between the main stellar characteristics (temperature, color, spectral class, luminosity), be able to use the Hertzsprung–Russell diagram, distinguish between main sequence stars, white dwarfs and giants (supergiants);
• p. 5.4.3: know the main stages of the evolution of stars like the Sun and massive stars, compare the duration " life cycle» stars of different masses, represent the evolutionary path of a star on the Hertzsprung–Russell diagram;
• p. 5.4.4: know the structure of the Galaxy and the main scales of our Galaxy, types of galaxies, understand the meaning of physical quantities: astronomical unit, parsec,

Task 24, like other similar tasks in the examination paper, is scored a maximum of 2 points if both elements of the answer are correct and 1 point if an error is made in one of the elements. The order in which the numbers are written in the answer does not matter. As a rule, tasks will be contextual in nature, i.e. Some of the data required to complete the task will be presented in the form of a table, diagram or graph.

Part 2 is left unchanged.

How not to fail physics?

To get the minimum initial score (36 points), you need to complete 9 tasks out of 32.

The most difficult tasks are:

• complex analysis of physical processes (these are multiple choice tasks);
• quantum physics;
• electromagnetic waves.

The following sections cause the least difficulty:

• mechanics;
• molecular physics;
• electricity.

These are more visual areas of science, so it is easier to explain and easier to understand.

You can practice solving problems using the open task bank, which is located on the FIPI website. The tasks in this bank are practice questions and are similar to those that will appear on the exam.

Analysis of the demo version of the Unified State Examination in Physics -2019 can be viewed here:

In some tasks, there are several correct solutions, which is why different interpretations of the correct completion of the task are possible. Don't be afraid to appeal if you think your score was calculated incorrectly.
