Language of instruction


Teaching methods

Lectures and written exercises.
The lectures will mostly focus on presenting theory, but instruction in simulation tools will also be provided.


Mandatory task
Five of Six assignments (hand-in exercises) have to be approved in order to take the final exam.

3 hours written exam.
Grading scale is from A (highest) to F (lowest), with E as the minimum pass grade

There will be arranged a re-sit exam for this course

Date for examination

Written exam 11.06.2019

The date for the exam can be changed. The final date will be announced in the StudentWeb early in May and early in November.
