Exams
Being an FI and Ground Examiner myself, I would suggest that you at least start on the reading particularly if you are going to do in on an intensive basis.
My reasoning is that if you leave it you will be under quite a lot of pressure to get everything done. I have found with the students that are underway with the reading and have a few exams under their belt generally speaking, perform better than the ones that turn up on their first day and haven't opened a book.
