**18. Requirements and grading (signature) procedure:**
Two midterm tests will be administered during the semester. To achieve at least a passing grade for the continuous assessment, submission of the semester homework and achieving at least a passing grade in each of the two midterms are required. The semester grade is the rounded-up average of the two midterm grades. Meeting the expected learning outcomes in full is also a prerequisite for a passing grade.
**19. Make-up opportunities:**
Homework can be submitted until the end of the semester. Each midterm can be retaken once during the semester and again during the make-up period if necessary.
