Podmínkou získání zápočtu je vypracování a odevzdání referátu o naměřených úlohách v rámci praktického cvičení k předmětu. Povaha kontroly studia předmětu vylučuje opravné termíny zápočtu.
Předmět je zakončen ústní zkouškou. Požadavky u zkoušky odpovídají sylabu předmětu v rozsahu, který byl prezentován na přednášce. Ke zkoušce se uchazeč přihlašuje po získání zápočtu. U zkoušky student dostává typicky 2-3 dílčí otázky a má 30 min. na přípravu (další doplňující otázky v průběhu zkoušky nejsou vyloučeny). Last update: Přech Lubomír, doc. RNDr., Dr. (06.10.2017)
