Way of continuous check of knowledge in the course of semester

Conditions for credit: Student must work out three tests. Student can receive up to 3 points for each of tests. Maximum number of points student can gain through tests is 3 * 3 = 9 points. Student can gain up to 12 points from the laboratory exercises (6 * 2 = 12 - 2 points each problem). Student can gain up to 9 points from the computer exercises (3 * 3 = 9 - 3 points each problem). Student can gain up to 14 points from the project. To pass the excercises part of course student has to gain at least 26 points. Student can gain up to 56 points from the final exam (circuit work - 32 points, oral part - 24 points). To pass the course student has to gain at least 51 points.
