Some clarifications


Exam hints

Verify whether your exam exercise sheets are complete: It should contain Exercise 1 to Exercise ??. Insert your name and matrikel (student number) on each sheet. Approaches, solutions and all side calculations must be written to the given paper. Please use also the back sides. If you need extra paper ask the supervisor. Do not remove the staple!
Do write with blue or black ink!
Do not use a pencil or any other erasable pen.  
The exam must be handled independently. Permitted auxiliary means are: writing materials, a pocket calculator (non-programmable, without division with remainder, without linear algebra software), and a crib sheet, DIN A4, two-sided, written only with your own handwriting. Any other utilities, even own paper, are not permitted.
An attempt at deception leads to failure for this exam and possibly other measures - even if the attempt is only detected later.  

The exam will carry the hints displayed on the right.

The exam is about the entire course. Please note that the second exam is for repetitions.

The exam is offered twice a year. There is no further limit on the number of attempts.
