Exam date (doodle)

There is now a doodle for the exam date here:

Rules: you can only say no to dates where you have a conflicting exam. No holidays, Christmas parties etc. If there are dates where you would like the exam not to be, please use the "Yes, if need be" option (yellow marking), and I will try to take that into account.
