Weekly exercise sessions

The weekly exercise sessions will take take place on Fridays 12.15-14. The exercise sets will usually be made available on Thursdays the week before, on the web-page and in the schedule. The set for Friday January 27 is now available. Two of the extra exercises (1 and 3) don't require any knowledge of what will be covered during the first lecture on Tuesday January 24, so you can have a look at these already now!
