Grading:

Oral exam, or the mark based on the CLOSING TEST (only good (4) or excellent (5) grade is offered).

Closing test:

  • date: 14. December, 12:00-14:00
  • place: A110

In the CLOSING TEST, you have to give the basic equations, definitions and diagrams asked, answers to multiple choice questions, and write a short essay about some of the topics of the topic list given.

If the result of the CLOSING TEST is above 75%, a grade is offered based on this test (good (4) above 75%, ecxellent (5) above 90%); if this grade is accepted, there is no oral exam.

Oral exam:

The oral exam begins with a SHORT TEST. In doing so, the student proves his/her preparedness by giving the basic equations, definitions and diagrams asked. The failure of the sort test (less than 50%) results in an fail (1) grade.
Students who successfully answer 50% of the questions of the SHORT TEST pick two topics of the topic list and after some preparation time, they should talk about these topics: they should begin with explanations of the topics and then answer to the questions that arise. Tha grade is given based on this oral exam.
The short test preceding the exam does not have to be written if the student has achieved at least 50% on the CLOSING TEST.
