Increasingly, ninth-graders are taking computer science tests as part of the OGE. This subject is considered extremely simple for some students, while others do not even try to pass it, because there is a high risk of remaining in the ninth grade next year.
Each examinee needs to know that even before completing the second part of the work, namely writing code, it is necessary to indicate what software the student is familiar with and with the help of what programming language the child will perform this task. What is the best way to prepare for the OGE in computer science?
How will the exam be conducted?
To complete this task, the student is given a computer. The following programming languages can be used:
- Basic;
- Pascal.
The last task number “20” from the OGE in computer science is divided into two options. The student is asked to choose one of them.
The first part of the work contains tasks not only of a basic level, but also of an increased level of complexity. Some of them require you to indicate only a number. In others, you will need to write consecutive characters.
Check your level of knowledge on the OGE in computer science
How are assignments graded?
Assignments, depending on their level of difficulty, have different degrees and criteria for assessment. In the first part, you can get only one point for each task in the OGE tests in computer science.
For all tasks in the exam paper, you can get 22, and five of them will be enough to get a “3” for the work in a five-point system. In order to write the exam, the student is given a total of 150 minutes of time.
Mark conversion scale
Where is the best place to prepare?
To successfully prepare for exams, each student uses different methods that will be most convenient to use. Some people find it more convenient to use the services of a tutor, or to use extracurricular literature in preparation.
Sites with tests and answers to them
To successfully solve the OGE in computer science, you can use such resources as “Yandex OGE”, “Dunno”, “Solve”. There is big choice assignments and tests that can be taken online. If you solve at least half of them, the likelihood of passing your work with an excellent grade will increase significantly.
Yandex OGE website in computer science
The well-known portal “Dunno” will allow you to download any options in PDF format. After that, you can print them out and try to solve them in writing, as will be the case in the exam itself, because there won’t be a second attempt. And if there are strikethroughs when answering a question, the result will not be counted.
Dunno website
It’s worth using the “Solve OGE” website.
Website I will solve the OGE
There you can not only solve an unlimited number of tasks in computer science, but also transfer your statistics to the teacher so that he can assess the level of preparation of his student.

control measuring materials
to be held in 2017
main state exam
in COMPUTER SCIENCE and ICT
1. Purpose of CMM for OGE– to assess the level of general educational training in computer science and ICT of IX grade graduates of general education organizations for the purpose of state final certification of graduates. The exam results can be used when admitting students to specialized classes in secondary schools.
OGE is conducted in accordance with Federal Law Russian Federation dated December 29, 2012 No. 273-FZ “On education in the Russian Federation.”
2. Documents defining the content of CMM
3. Approaches to content selection and CMM structure development
The examination paper covers the main content of the computer science and ICT course. The most significant material is covered, which is clearly interpreted in the majority of computer science and ICT course options taught at school and is included in the Federal component of the state educational standard of basic general education.
The content of the assignments is developed on the main topics of the computer science and ICT course, combined into the following thematic blocks: “Representation and transmission of information” (sections 1.1 and 1.2 of the codifier), “Information processing” (sections 1.3 and 1.4 of the codifier), “Basic ICT devices” (section 2.1 of the codifier), “Recording by means of ICT information about objects and processes, creation and processing information objects"(sections 2.2 and 2.3 of the codifier), "Design and modeling" (section 2.5 of the codifier), "Mathematical tools, spreadsheets" (section 2.6 of the codifier), "Organization of the information environment, information retrieval" (sections 2.7 and 2.4 of the codifier).
The work does not include tasks that require easy playback knowledge of terms, concepts, quantities, rules. When performing any of the tasks, the examinee is required to solve a problem: either directly use a known rule, algorithm, skill; or choose the most suitable one from the total number of studied concepts and algorithms and apply it in a known or new situation.
Part 2 of the work contains practical tasks that test the most important practical skills of the computer science and ICT course: the ability to process a large information array of data and the ability to develop and write a simple algorithm.
Examination tasks do not require students to have specific knowledge operating systems And software products, skills to work with them. The elements being tested are the basic principles of presentation, storage and processing of information, skills in working with such categories software, as an electronic (dynamic) table and a formal executor’s environment, rather than knowledge of the features of specific software products.
The practical part of the work can be performed using various operating systems and various application software products.
4. Connection of the OGE exam model with the Unified State Exam KIM
A significant part of the tasks with a short answer are similar in type to the Unified State Examination tasks in computer science and ICT, but in content and complexity they correspond to the level of basic general education. At the same time, the work includes tasks from some sections of the computer science course that are not included in the Unified State Exam in computer science and ICT (for example, tasks related to the technology of processing large amounts of data in spreadsheets).
One of the differences in the structure of the OGE KIM is the format of part 2 of the work (tasks with a detailed answer). Unlike the Unified State Exam, where Part 2 is performed on a form and the result of the work is a written solution, checked by an expert, in the Unified State Exam Part 2 is performed on a computer and the checked result of the task is a file. This allows you to significantly expand the possible topics of assignments and the variety of skills being tested, as well as in the future move to an exclusively computer-based form of passing the exam.
5. Characteristics of the structure and content of CMM
The examination paper consists of two parts.
Part 1 contains 18 tasks basic and advanced levels of difficulty, including 6 tasks with the choice and recording of an answer in the form of a single number and 12 tasks that require the examinee to independently formulate and record the answer in the form of a sequence of symbols.
Part 2 contains 2 tasks high level difficulties. The tasks in this part involve practical work students at the computer using special software. The result of each task is separate file. Task 20 is given in two versions: 20.1 and 20.2; The examinee must choose one of the options for the task.
The training version of the OGE 2017 in computer science, version 1 with answers, is modeled after the demonstration version of 2017.
The work consists of two parts, including 20 tasks. Part 1 contains 18 short answer tasks, part 2 contains 2 tasks that must be completed on the computer.
