TIMETABLE

Lectures:	Thursday 13:10 in Praktikum KPMS	(doc. RNDr. Daniel Hlubinka, Ph.D.)
Exercise class:	Tuesday 10:40 in K4

ANNOUNCEMENTS

In the first few weeks of semester the slot of the exercise class will be used for the lecture as well.

On Monday, December 11 at 14:00 in Praktikum KPMS there will be an extra exercise class (will be compensated by shorter lectures).

The last assignment will be related to Exercise No. 7 being held before the Christmas break.

EXERCISE CLASS MATERIALS

REQUIREMENTS TO GET A COURSE CREDIT (ZÁPOČET)

The course credit for the exercise class will be awarded to the student who hands in a satisfactory solution to each assignment by the prescribed deadline which is 1st January 2024 (20:24 CET). The nature of these requirements precludes any possibility of additional attempts to obtain the exercise class credit.
