Course completion requirements - Czech

Získání zápočtu je podmínkou pro konání zkoušky.

Udělení zápočtu je podmíněno průběžnou účastí na výuce, aktivitou při cvičeních a úspěšným absolvováním závěrečné písemky.

Povaha kontroly studia předmětu vylučuje opakování této kontroly, zápočet se tedy opakovat nedá.
