For each CFU (25 hours), the following are scheduled:
- 2 hours of delivered teaching - DE (content presentation through slides, scientific papers, and videos)
- 2 hours of interactive teaching - DI (guided online exercises in audio-video streaming)
- 19 hours of self-study on the bibliography texts, provided slides, and indicated scientific articles.

To facilitate inclusive teaching, the instructor offers up to two hours per week for office hours, by appointment.

- Written exam, consisting of 22 multiple-choice questions (1 point for each correct answer) and 3 open-ended questions, one of which is on the book of choice, evaluated based on comprehensiveness, relevance, and clarity of exposition for up to 9 points (cut-off for passing = 18 points), with the possibility of requesting an additional oral exam (upon request within 2 days of the publication of the written exam results by emailing the instructor);
- Oral exam (upon request 3 days before the exam by emailing the instructor), consisting of 3 questions, the first of which is on a topic of the student's choice.

For the academic year 2024/2025, the exam, whether oral or written, covers the content of the slides uploaded on the KIRO portal, the mandatory text, and the chosen text.

It is not advisable to refuse the obtained grade more than once. The student is required to accept the grade achieved in the last exam session taken.
