Back in October, I studied up till two days before the exam. That way, I never felt bad about not studying enough. The day before, I relaxed. It worked.
i didn't look at any "new" problem types or subjects @ 1 week out. I did do about a 30-45 min review of my notes and organizational stuff the night before but didn't look at problems/solutions. I felt better giving my eyes one last look in case I saw something I could pinpoint during the exam.
