Final weeks in GR

Just a short summary of the `final events' in the GR course, as indicated today during the lecture:

• Mon 30/05: final group exercise session (see the problem set)
• Fr 27/05 and Tue 31/05: final two lectures (on cosmology)
• Fr 10/06: Q&A session

 The Q&A session is during the week before the exam, and I will (try to) answer, and discuss, any GR-related question that you may have. So the more you prepare for the exam already until that day, the more you will get out of this session...
