Grading:
Weekly exercises 25%
Exam 75%
Weekly exercises are due each Monday at 9 am, between
September 14 and October 5, to be returned to the grey metallic mailbox by the
Northern entrance of the Borealis Building.
Discussion of the last weekly exercise
at October 7, 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.
