• oral exam
• laboratory work
• computer skills
Notes:
The student must finish each part of the exam (written part of the exam, oral part of the exam, defence of laboratory work, defence of computer skills) with at least 50%.
In the case of two midterm tests, which can replace written exam, each of them has to be done with at least 50% to pass the written exam successfully.
