zápočet: v případě prezenční výuky přítomnost na cvičeních, odevzdání protokolů (správně vyřešenách) a zadané projektové práce
V případě distanční výuky odpadá požadavek na povinnou přítomnost na cvičeních, ostatní požadavky zůstávají (tedy správně vypracované odevzdané protokoly a odevzdaná projektová práce na zápočet; písemná zkouška). |
