Grading:

Weekly exercises 25%

Exam 75%

Weekly exercises are due each Monday at 9 am, between January 21 and February 11, to be retuned to the Lecturer’s mailbox by the Southern entrance of the Borealis Building.

Discussion of the last weekly exercise at February 13, 08-10 at BOR102.

In addition, there are experimental exercises during February, as well as reporting sessions in early March. The experimental exercises are supervised by Dr. Pekka Tynjälä. Experimental exercise is predominantly group work, and does not affect grading.

Experimental exercise February 15, 2013, at 08:30, room Bor 176.
