Learning methods and activities

Lectures and independent exercises. The number of mandatory exercises is stated at the start of the semester. Mandatory exercises must be delivered according to specified deadlines and must be approved in order to take the exam.

Further on evaluation

Written exam, digital. Grade: Letter grades.

Approved mandatory work requirements are valid up to and including the following academic year.

Re-sit exam in August (can be conducted as oral).

In the case of applications for crediting, approving of subjects from previous cohorts or other institutions' corresponding education programs, each application will be processed individually and the applicant must be able to include credits reduction on overlapping subjects.
