Explanatory note

6 variants of final tests for assessing the quality of training of graduates of the basic school are presented. Each option contains 24 questions, with the help of which the teacher can check the quality of assimilation of the material covered. Each question has 4 possible answers, 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' training in all topics of the informatics 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 course material included in the mandatory minimum content.

Test run time: 30 min.

Evaluation criteria:

Number of correct answers

Less than 10

10 – 14

15 – 19

20 – 24

Tests are compiled on the basis of the "Mandatory minimum content of education in computer science"
