Examination including compulsory elements

A written exam. Non-obligatory hand-in questions and a voluntary "mid-period exam" give bonus points for the exam.

The course examiner may assess individual students in other ways than what is stated above if there are special reasons for doing so, for example if a student has a decision from Chalmers on educational support due to disability.
