Grading:
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).
