Grading:

Weekly exercises 25%

Exam 75%

 

Weekly exercises are due each Monday at 9 am, between September 12 and October 3, to be returned to the grey/green metallic mailbox by the Northern entrance of the Borealis Building.

Discussion of the last weekly exercise at October 5, 08-10 at N106.

 

In addition, there is an experimental exercise by September 30.  Reporting session by October 7. The experimental exercises are supervised by Dr. Pekka Tynjälä. Experimental exercise is predominantly group work and does not affect grading.
