PREZENČNÍ STUDIUM Podmínky pro udělení zápočtu na cvičení: - 100 % účast na teoretických cvičeních – 2 body - účast na teoretickém cvičení menší než 79% ( více než 3 neúčasti) poskytuje možnost neudělení zápočtu - úspěšné absolvování dvou samostatných výpočtových písemek – hodnocení 18+18 = max. 36 bodů - oprava písemky – lze opravit maximálně jednu písemku maximálně jedenkrát. Bodové hodnocení zápočtu: - zápočet min. bodů 12 - zápočet max. bodů 38 V celkovém zisku bodového ohodnocení zápočtu musí být obsaženo nenulové hodnocení obou výpočtových písemek (min. 6 bodů za písemku), tzn. student musí absolvovat obě výpočtové písemky. Bodové hodnocení zkoušky: zkouška kombinovaná - písemná část zkoušky - max. bodů 12 - ústní část zkoušky - max. bodů 50 V celkovém zisku bodového ohodnocení zkoušky musí být obsaženo jak nenulové hodnocení výpočtové zkouškové písemky (min. 4 body za písemku) tak nenulové hodnocení vlastní ústní zkoušky, tzn. student musí absolvovat obě části zkoušky. Bodové hodnocení předmětu se získá součtem bodů za cvičení a za absolvování zkoušky. Výsledná klasifikace je dána podmínkami ve Studijním a zkušebním řádu VŠB TUO.
