Lectures, practical classes, individual independent work.

Solving problems in practical classes for the semester - a maximum of 10 points; Testing (2 tests of 10 points); Homework and individual tasks - 10 points; Modular test (2 Modular tests of 10 points each); Exam - 40 points. The exam ticket consists of 2 theoretical questions (answers, questions are evaluated on 10 points) and 2 tasks, which are evaluated on 10 points. In total, you can get from 0 to 40 points for the exam. The condition for achieving a positive grade for the discipline is to obtain at least 60 points, the grade for the exam can not be less than 24 points. Conditions for admission to the final exam: a bachelor's degree in total is not less than the critical-calculated minimum for the semester. Bachelors who scored less than the critical minimum of 36 during the semester must write an additional test in order to be admitted to the exam.
