Last update: Mgr. Jan Hubička, Ph.D. (28.02.2018)

For passing the class you should obtain at least 70% of total marks from the tests given during the semester and a practical programming homework. Students can obtain addidional marks by homework (the amount of homework depends on missing marks). Homework will be given at the end of the semester if someone needs it.

Requirements to the exam -
Last update: Mgr. Jan Hubička, Ph.D. (28.02.2018)

There will an examination consisting of a written and oral part.

The written part involves several exercises. The oral part involves discussion of solutions to the set problems and additional questions on topics covered in lectures and classes.

Class credits ("zapocet") are prerequisite for taking the examination
