PREFACE .
One of the main tasks of modern education is the use of information technology in the educational and cognitive activities of students.

The large number of students in the classes of secondary schools and the time limitation of the lesson do not make it possible to fully implement the important educational principle of teaching - an individual approach to each student. In this regard, tasks with a selective response form are most common. They make it possible to control students’ knowledge using additional technical means, for example, a personal computer, which saves time as much as possible.

This manual offers test tasks for programmed testing of knowledge, which will allow the teacher to more often check the level of knowledge, skills and abilities of students with a minimum investment of time.
The proposed final tests consist of thirty options with twenty-four tasks each. They can be used in full for final certification or partially for thematic ones.

The tests are compiled in accordance with the requirements of the program of the Ministry of Education and Science of the Russian Federation for general education institutions.
