How to write a program in exam. Exam courses in computer science. How long does it take to prepare for the exam in computer science from scratch?

The Unified State Exam courses in informatics, organized by our training center, are irreplaceable help in mastering gaps in the subject, useful both for future specialists and those who wish to masterfully master the knowledge of the real IT sphere. Classes in a modern computer class conducted from scratch, at the end of which the students will be "armed" with the basics of the professions of the future.

Our USE courses in computer science are:

• fundamental knowledge;
• the ability to model a variety of objects, systems and processes;
• the ability to apply knowledge in practice;
• consultations of experienced specialists before the training work of StatGrad;
• training in computer science for the exam.

Our goals and objectives - it is to provide quality training with subsequent high scores in exams. We consider the main priorities in teaching grades 10-11:

• preparation for the successful passing of the Unified State Exam in computer science for a high score;
• obtaining basic knowledge of programming in the most common algorithmic languages;
• to generalize and systematize school knowledge in computer science, eliminating all the "gaps" and shortcomings;
• consider algorithms for solving the most common problems, as well as problems of increased complexity in computer science;
• develop logical thinking skills for solving non-standard USE problems in computer science.

USE courses in informatics at the FIRST USE CENTER give listeners a unique opportunity to take interesting classes, during which it will be possible:

• repeat all sections of the school computer science course and improve academic performance;
• sort out all types of USE tasks in computer science and learn how to find algorithms for their solution;
• get training for the exam in computer science;
• use the acquired knowledge and skills in practice and everyday life.

Benefits of learning

By receiving preparation for passing exams in our center, students receive a large number of advantages:

• groups for teaching computer science at the FIRST USE CENTER are formed on the basis of an introductory test, which determines the initial level of preparation of each student;
• after the introductory testing, students are assigned to groups for training, depending on their initial level of training. The group size is no more than 8 people, which allows the teacher to apply both an individual and a group approach to teaching;
• the teachers of informatics of the FIRST USE-CENTER are professional teachers who have been trained under the "Expert USE" program. Therefore, we do not just teach to solve the tasks of the KIM USE in computer science, we also explain the structure of tasks, teach how to properly allocate time for the exam, and also conduct psychological training before the exam
• the educational programs of our USE courses in computer science are the author's developments of the USE-CENTER methodologists and take into account not only all the requirements of FIPI, but also the personal ability of each student to learn;
• during the training, students pass several control and rehearsal trial examinations in computer science on official forms of the FIPI.

Comfortable conditions that are provided to all students of the FIRST USE CENTER, a friendly atmosphere and confidence in one hundred percent success in 2020 will help to cope with the upcoming exam tests. A lesson in computer science and ICT for grades 10 and 11 in our center is the future foundation of great opportunities.

For effective training in computer science, a brief theoretical material is given for each task to complete the task. Selected over 10 training tasks with analysis and answers, developed on the basis of demo versions of previous years.

There are no changes in the KIM USE 2020 in informatics and ICT.

Areas in which knowledge testing will be carried out:

• Programming;
• Algorithmization;
• ICT tools;
• Information activity;
• Information processes.

Action to be taken when preparing:

• Repetition of the theoretical course;
• Decision tests in informatics online;
• Knowledge of programming languages;
• Improve mathematics and mathematical logic;
• To use a wider range of literature - the school curriculum is not enough for success on the exam.

Exam structure

The duration of the exam is 3 hours 55 minutes (255 minutes), one and a half hours of which it is recommended to devote to the tasks of the first part of the CMMs.

Tasks in tickets are divided into blocks:

• Part 1- 23 tasks with a short answer.
• Part 2 - 4 problems with a detailed answer.

Of the proposed 23 tasks of the first part of the examination work, 12 refer to the basic level of knowledge testing, 10 - increased complexity, 1 - high difficulty level. Three tasks of the second part of a high level of complexity, one of an increased level.

When making a decision, it is obligatory to record a detailed answer (free form).
In some assignments, the text of the condition is submitted in five programming languages \u200b\u200bat once - for the convenience of students.

Points for Computer Science Assignments

1 point - for 1-23 tasks
2 points - 25.
3 points - 24, 26.
4 points - 27.
Total: 35 points.

To enter a middle-level technical university, you must score at least 62 points. To enter the capital university, the number of points must correspond to 85-95.

To successfully write the exam paper, you must have a clear command of theory and constant practice in solving tasks.

Your formula for success

Work + work on mistakes + carefully read the question from start to finish to avoid mistakes \u003d maximum score on the exam in computer science.

With the modern world of technologies and realities of programming, development Unified State Exam in Informatics has little to do. There are some basic points, but even if you understand the tasks a little, this does not mean that you will eventually become a good developer. But there are a great many areas where IT specialists are needed. You will not be wrong if you want to have a stable income above average. In IT, you get it. Provided, of course, the availability of appropriate abilities. And you can develop and grow here as much as you like, because the market is so huge that you can't even imagine! Moreover, it is not limited only to our state. Work for any company from anywhere in the world! This is all very inspiring, so let the preparation for the exam in computer science be the first minor step, followed by years of self-development and improvement in this area.

Structure

Part 1 contains 23 tasks with a short answer. This part contains tasks with a short answer, implying an independent formulation of a sequence of symbols. The assignments check the material of all thematic blocks. 12 tasks refer to the basic level, 10 tasks to the increased difficulty level, 1 task to the high difficulty level.

Part 2 contains 4 tasks, the first of which is of increased difficulty level, the other 3 tasks of high difficulty level. The tasks of this part involve writing a detailed answer in any form.

The examination work takes 3 hours and 55 minutes (235 minutes). It is recommended to devote 1.5 hours (90 minutes) to the tasks of Part 1. The rest of the time is recommended to be devoted to the tasks of Part 2.

Assignment Grading Explanations

Each task of part 1 is estimated at 1 point. The task of part 1 is considered completed if the examinee gave an answer corresponding to the code of the correct answer. Completion of tasks in part 2 is estimated from 0 to 4 points. The answers to the tasks of part 2 are checked and evaluated by experts. The maximum number of points that can be obtained for completing the tasks of part 2 is 12.

What programming language to choose, what tasks to focus on and how to allocate time on the exam

Teaches computer science at Foxford

Different universities require different IT entrance exams. Somewhere you need to pass physics, somewhere - computer science. Which exam to prepare for is up to you, but it should be borne in mind that the competition in the specialty where you need to pass physics is usually lower than in the specialties where the USE in computer science is required, i.e. the probability to enter "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 the chosen specialty.

What you need to know about the exam in computer science

The Unified State Exam in Informatics consists of two parts. In the first part there are 23 problems with a short answer, in the second - 4 problems with a detailed answer. The first part of the exam contains 12 basic-level assignments, 10 advanced-level assignments and 1 high-level assignment. In the second part - 1 task of an advanced level and 3 - a high one.

Solving problems from the first part allows you to score 23 primary points - one point for the 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 to test scores, which are the result of the USE. 35 primary points \u003d 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 the problems of the first part. Each primary score obtained in the second part of the exam will give you 3 or 4 test points, which in total is about 40 final exam points.

This means that when performing the Unified State Exam in Informatics, 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 gain more final points. But the cost of an error during their implementation is higher - the loss of each primary point is fraught with the fact that you will not pass the competition, because 3-4 final points for the exam with high competition in IT specialties can be decisive.

How to Prepare for Part One Challenges

• Pay special attention to tasks number 9, 10, 11, 12, 15, 18, 20, 23. These tasks, according to the analysis of the results of the past years, are particularly difficult. Difficulties with the solution of these problems are experienced not only by those who have a low overall score for the Unified State Exam in computer science, but also "good students" and "excellent students".
• Memorize the table of powers of number 2.
• Remember that Kbytes in tasks means Kibybytes, not Kilobytes. 1 kibibyte \u003d 1024 bytes. This will help to avoid computational errors.
• Carefully study the options for the USE from previous years. The computer science exam is one of the most stable, which means that you can safely use the USE options for the last 3-4 years for preparation.
• Get to know the different options for wording tasks. Remember that minor wording changes will always result in worse exam results.
• Read the problem statement carefully. Most of the errors in completing assignments are associated with a misunderstanding of the condition.
• Learn to independently check completed assignments and find errors in answers.

What you need to know about solving problems with a detailed answer

Task 24 - to find an error

25 task requires drawing up a simple program

26 problem - on game theory

27 task - it is necessary to program a complex program

The main difficulty in the exam is 27 problems. It can be solved only60-70% of those writing the exam in computer science. Its peculiarity lies in the fact that it is impossible to prepare for it in advance. Every year a fundamentally new problem is presented for the exam. When solving problem # 27, not a single semantic error should be allowed.

How to time your exam

Focus on the data that are given in the specification of control measuring materials for the exam in informatics. It indicates the approximate time allotted for completing the tasks of the first and second parts of the exam.

The exam in computer science lasts 235 minutes

Of these, 90 minutes are devoted to solving problems from the first part. On average, each task from the first part takes 3 to 5 minutes. It takes 10 minutes to solve problem 23.

There are 145 minutes left to solve the tasks of the second part of the exam, while solving the last problem # 27 will take at least 55 minutes. These calculations were carried out by specialists from the Federal Institute for Pedagogical Measurements and are based on the results of past exams, so they should be taken seriously and used as a guide for the exam.

Programming languages \u200b\u200b- which one to choose

1. BASIC. It is an outdated language, and although it is still taught in schools, there is no point in wasting time mastering it.
2. School algorithmic programming language. It is designed specifically for early learning in programming, convenient for mastering the initial algorithms, but practically does not contain depth, there is nowhere to develop in it.
3. Pascal. It is still one of the most common programming languages \u200b\u200bfor teaching in schools and universities, but its capabilities are severely limited. Pascal is quite suitable as a writing language for the exam.
4. C ++. A universal language, one of the fastest programming languages. It is difficult to learn from it, but in practical application its possibilities are very wide.
5. Python... It is easy to learn at an elementary level, the only thing that is required is knowledge of English. At the same time, with an in-depth study of Python, it provides the programmer with no less opportunities than C ++. Having started learning "Python" at school, you will use it in the future, you do not have to relearn to another language in order to reach new horizons in programming. To pass the exam, it is enough to know "Python" at a basic level.

Good to know

• Computer science works are evaluated by two experts. If the experts' assessment results differ by 1 point, the higher of the two points is given. If the discrepancy is 2 points or more, the work is rechecked by a third expert.
• A useful site for preparing for the exam in computer science -

In the exam paper, the exam, several tasks require knowledge of the programming language. In tasks 8, 11, 19, 20, 21, 24, you need to understand and analyze the text of the program, in task 25 you need to write a fragment of the program. In the formulation of the problem, the following languages \u200b\u200bare provided to choose from: BASIC, Pascal, C, Algorithmic language, Python, Natural language.

The only task in which you need to write a complete program yourself is task 27. In the task formulation, you need to write a program “in any programming language”. So which programming language should you choose?

I will express my personal opinion on this, based on the experience of my students passing the exam over the past few years. In the 27th problem of the exam, it is necessary to correctly compose an algorithm, which can be implemented in almost any programming language. Those. in one language the program will be shorter, in another it will be longer, but so far there has never been a problem that could not be solved, for example, in BASIC. In addition, the choice of language does not affect the score. Therefore, if you are fluent in some exotic programming language, you have every right to write a program in it. However, one should take into account the fact that the program will be checked and evaluated.

The FIPI recommendations to the inspectors say: "If the expert is not familiar with this programming language, then he should use the available reference literature or seek help from the consultant or the chairman (deputy chairman) of the subject commission, while observing the inspection regulations." Those. in the case when the inspector has encountered a language unknown to him, he must "observe the inspection regulations", i.e. within the allotted time (and when checking the exam, they are very short), find someone who knows this programming language, and understand the text of your program. Obviously, the probability of underestimation is very high. In addition, it should be understood that schools only use licensed (officially purchased) software. If the school has not purchased the compiler for the language you are using, it will be impossible to test the functionality of your program on your computer.

The practice of the last two years has shown that many assessors do not know the Python language (it appears in the list of allowed languages \u200b\u200bin the USE problems for only the second year). Verification of the text of a program written in C #, Java causes difficulties for the reviewers. Not to mention the rare specific languages. I do not recommend writing a program in a natural or algorithmic language, due to the lack of official rules describing the language. And it is not very pleasant to understand the text written in a language that is not used in practice. I always strongly advise students to describe the algorithm of the program in natural language in order to facilitate the task of the examiner, but the program itself should be written in an understandable, convenient programming language.

For now, I recommend choosing Pascal, C or Basic. These are well-known, common languages. There is a development environment for them in almost any school. This means that the examiner will not have any questions while analyzing your program. The Pascal language has one more advantage: the initially difficult 27th problem was solved in it, which means that you can easily find examples, samples of solutions and analyzes of all types of problems in the literature and on the Internet, which cannot be said about other languages.
