Exercise group sessions before the midterm exam

There will be two exercise group sessions before the midterm exam, where selected exercises from the lecture notes and problems from previous exams will be gone through at the black board. The first of these sessions will be Thursday 18.09 at 10:15.

If there are any special requests for specific problems to be solved, send an email to ainard@astro.uio.no, and I'll see if I can include them.
