This is a VU. The 2 hours of lecture will be complemented by student contributions which vary with the weeks from calculation and computing exercises over paper reports and lectures summaries.

Art der Leistungskontrolle und erlaubte Hilfsmittel

- Weekly ungraded exercises provide the required feedback and training
- Presence in 80% of the exercises is mandatory.
- There will be 2 written tests (à 1 hour ), one in the middle and one at the end of term.
You pass the test with >50% of all possible points. The scale above that is linear.
- Every student will prepare twice a written Latex summary of a lecture sessions (supported
by the info slides and books that we provide) and report on this as a review in the first 20
min of an exercise.

Total Grade:
25% first summary: written and oral presentation
25% 2nd summary: written and oral presentation
25% 1st written test
25% 2nd written test
