Does your program have comprehensive exams and what are they like? I've recently spoken with students at other schools who seem to have exams that are structured much better than in my PhD program. Ours are at the end of Year 4. They are two days of 8 hours a day. We get 2 mandatory questions each day and then must choose 6 out of 10 others to answer. It's a total of 4 mandatory and 12 self selected questions. There's no reading list. We are only told the date the exam will be held and that the questions can be on anything in our field. We must know names of articles, names of authors and dates of publication. Tell me about yours.
