Repeat, repeat, repeat. We can't say enough about repetition when it comes to practicing and studying questions. You'll find that the earlier you start your studies and the more time you spend review and re-reviewing the topics and questions, the more successful you will be. Giving yourself enough time before the exams to go over the M5 multiple times will prove to be time well spent and will help to lower your stress level when sitting down to take the real exam.
