Small tests during the semester. The practice mark is calculated from these small tests and the two big tests.

Visiting the practice course is compulsory.

Requirements of the practice mark:

Visiting the practice courses is compulsory

Get mark 2 for both big tests

Practice mark:

The overall average of the two big test’s mark and the average of the small tests:
practice mark = (big test 1 + big test 2 + average of small tests)/3
