Teaches computer science at Foxford

Different universities require different entrance exams for IT areas. Somewhere you need to take physics, somewhere you need to take computer science. It’s up to you to decide which exam to prepare for, but it’s worth keeping in mind that the competition for specialties where you need to take physics is usually lower than for specialties where the Unified State Exam in computer science is required, i.e. the likelihood of enrolling “through physics” is greater.

Why then take the Unified State Exam in computer science?

It is faster and easier to prepare for it than for physics.
You will be able to choose from more specialties.
It will be easier for you to study in your chosen specialty.

What you need to know about the Unified State Exam in computer science

The Unified State Examination in computer science consists of two parts. The first part contains 23 problems with a short answer, the second - 4 problems with a detailed answer. The first part of the exam contains 12 basic level tasks, 10 advanced level tasks and 1 high level task. In the second part there is 1 task of an advanced level and 3 tasks of a high level.

Solving the problems from the first part allows you to score 23 primary points - one point for each completed task. Solving the problems of the second part adds 12 primary points (3, 2, 3 and 4 points for each problem, respectively). Thus, the maximum primary points that can be obtained for solving all tasks is 35.

Primary scores are converted into test scores, which are the result of the Unified State Examination. 35 raw points = 100 test points for the exam. At the same time, more test points are awarded for solving problems from the second part of the exam than for answering problems in the first part. Each primary score received for the second part of the Unified State Examination will give you 3 or 4 test points, which in total is about 40 final points for the exam.

This means that when completing the Unified State Exam in computer science, it is necessary to pay special attention to solving problems with a detailed answer: No. 24, 25, 26 and 27. Their successful completion will allow you to score more final points. But the cost of a mistake during their implementation is higher - the loss of each initial point is fraught with the fact that you will not pass the competition, because 3-4 final points for the Unified State Exam with high competition in IT specialties can become decisive.

How to prepare to solve problems from the first part

Pay special attention to tasks No. 9, 10, 11, 12, 15, 18, 20, 23. These tasks, according to the analysis of the results of past years, are especially difficult. Difficulties in solving these problems are experienced not only by those who have a low overall score for the Unified State Exam in computer science, but also by “good” and “excellent” students.
Memorize the table of powers of the number 2.
Remember that KBytes in tasks means kibibytes, not kilobytes. 1 kibibyte = 1024 bytes. This will help avoid errors in calculations.
Carefully study the Unified State Exam options of previous years. The computer science exam is one of the most stable, which means that you can safely use the Unified State Exam options from the last 3-4 years for preparation.
Get to know the different options for wording assignments. Remember that minor changes in wording will always lead to poorer exam results.
Read the task conditions carefully. Most errors when completing tasks are due to an incorrect understanding of the condition.
Learn to independently check completed assignments and find errors in answers.

What you need to know about solving long-answer problems

Task 24 - to find an error

Problem 25 requires writing a simple program

Problem 26 - game theory

Task 27 - you need to program a complex program

The main difficulty in the exam is problem 27. It can only be decided60-70% of those writing the Unified State Exam in computer science. Its peculiarity is that it is impossible to prepare for it in advance. Every year a fundamentally new task is presented for the exam. When solving problem No. 27, not a single semantic error can be made.

How to calculate time in an exam

Refer to the data given in the specification of control measuring materials for the Unified State Exam in computer science. It indicates the approximate time allotted for completing the tasks of the first and second parts of the exam.

The Unified State Examination in computer science lasts 235 minutes.

Of these, 90 minutes are allocated to solving problems from the first part. On average, each task from the first part takes from 3 to 5 minutes. It takes 10 minutes to solve problem No. 23.

There are 145 minutes left to solve the tasks of the second part of the exam, while solving the last problem No. 27 will require at least 55 minutes. These calculations were carried out by specialists from the Federal Institute of Pedagogical Measurements and are based on the results of previous years' exams, so they should be taken seriously and used as a guide for the exam.

Programming languages - which one to choose

BASIC. This is an outdated language, and although it is still taught in schools, there is no point in wasting time on mastering it.
School algorithmic programming language. It is designed specifically for early learning of programming; it is convenient for mastering initial algorithms, but contains virtually no depth and has nowhere to develop.
Pascal. It is still one of the most common programming languages for teaching in schools and universities, but its capabilities are also very limited. Pascal is quite suitable as a language for writing the Unified State Exam.
C++. A universal language, one of the fastest programming languages. It is difficult to learn, but in practical application its possibilities are very wide.
Python. It is easy to learn at a beginner level; the only thing required is knowledge of the English language. At the same time, with in-depth study, Python provides the programmer with no less opportunities than C++. Having started studying Python in school, you will continue to use it in the future; you will not have to relearn another language in order to achieve new horizons in programming. To pass the Unified State Exam, it is enough to know Python at a basic level.

Good to know

Computer science papers are assessed by two experts. If the experts' assessment results differ by 1 point, the higher of the two points is assigned. If the discrepancy is 2 points or more, the work is rechecked by a third expert.
