KSgirl86…it all depends how you study. For me, I do three 30 MCQ tests the morning before my exam and even if I notice areas I should have studied more…I don't bother studying since I won't learn it overnight. I recommend doing a brief review of the information that you think you should have studied more, but don't do anything in depth.
I find it better to be relaxed going into the exam instead of stressing over whether you know all the material. For all you know, the information you should have studied more, won't be on the exam.
I wish you the best of luck tomorrow with the exam.
