I take two weeks. I review for two whole weeks for 10 to 14 hours a day. I review, I don’t read any new material. And this is after at least 300 hours of studying. Just review notes, readings, Qbank and take practice exams.
Try to get 2 weeks at minimum. Not sure it is possible. Just start for level 3, much less time than level 1 and 2. I am doing too many things at the same time now.
