Planned learning activities and teaching methods

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.

Assesment methods and criteria linked to learning outcomes

Work of students is evaluated during study by tests in exercises. They can obtain maximum 70 points by these tests during semester. Final examination is evaluated by 70 points at maximum.
