Continuous assessment: open-book written test (a different test for each student) (75%) and individual assignment on one of the chapters defined by the instructor with presentation (25%). Minimum pass mark: 9.5 out of 20.
Exam-based assessment: same as written test (the work can be done from scratch or improved).
