There are no changes in the structure and content of the 2019 examination paper compared to 2018.

In this section you will find online tests that will help you prepare to take the OGE (GIA) in computer science. We wish you success!

The standard OGE test (GIA-9) of the 2019 format in computer science and ICT contains two parts. The first part contains 18 tasks with a short answer, the second part contains 2 tasks that must be completed on the computer. In this regard, only the first part (the first 18 tasks) is presented in this test. According to the current exam structure, among these 18 questions, only the first 6 questions offer answer options. However, for the convenience of passing tests, the site administration decided to offer answer options for each task. However, for tasks in which the compilers of real test and measurement materials (CMMs) do not provide answer options, we decided to significantly increase the number of these answer options in order to bring our test as close as possible to what you will have to face at the end of the school year.

Explanatory note

6 versions of final tests are presented to assess the quality of training of primary school graduates. Each option contains 24 questions with which the teacher can check the quality of mastery of the material covered. For each question there are 4 answer options, from which you must choose the correct one. The questions are selected in such a way that it is possible to determine the quality of students’ preparation in all topics of the computer science course included in the mandatory minimum content of education. The number of questions in each option may vary. The main thing is that each version of the final test fully covers all the theoretical and practical material of the course, included in the required minimum content.

Test execution time: 30 min.

Evaluation criteria:
