Worksheets are handed out on Fridays,
and are to be completed within the following week
(collection on Thursdays at 14:00 in front of the general office:
Put your solution into the TA's pigeonhole who is running the support
class you have signed up for).
Each worksheet contains four questions, and we will mark one of them
weekly at random, out of 10 points each time.
The weekly worksheets carry 15% assessed credit; the remaining
85% are carried by a two-hour examination.
