Weekly exercises 25%
Exam 75%
Weekly exercises are due each Monday
at 9 am, between September 16 and October 7, 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 9, 08-10 at Bor101.
In addition, there are experimental
exercises during October, as well as reporting sessions. The experimental
exercises are supervised by Dr. Pekka Tynjälä.
Experimental exercise is predominantly group work, and does not affect grading. October 4
(morning/afternoon).
