The credit is granted automatically after passing the exam.

Depending on the situation, the exam can have either a classical or a distance form. A part of the score for the exam comes from solving homework problems which will be published and their solutions handed in during the semester.

The classical form will consist of a written test, typically supplemented by an oral examination.

The distance form will consist of a combination of an on-line test and a mandatory video call.

Detailed infromation for this semester (in Czech) available at You will be informed about any changes due to the current development in a timely manner.
