Nutnou podmínkou připuštění ke zkoušce je získání zápočtu. Zkouška se sestává z písemné a ústní části. Písemná část spočívá ve vyřešení velmi snadného problému, který nevyžaduje dlouhé počítání (max. 30 min). Ústní část navazuje na řešení zmíněného problému a trvá max. 45 min. Známka zkoušky se stanoví ze souhrnného hodnocení písemné a ústní části. Požadavky zkoušky odpovídají sylabu předmětu v rozsahu, který byl odpřednášen
