Grading system
The cumulative grade is computed as follows:
C = 0,6 * H + 0,4 * T,
where H is the grade for the home assignments and T is the written test grade.
The final course grade is given by
F = 0,5 * C + 0,5 * E
where E is the final exam grade.
Grades in all formulas are rounded according to the standard rule.
