First of all, I'm assuming you have both practical as well as written exams for your anatomy class. My advice is to not buy Grants. They probably only require that because you're using Grant's Disector. Grant's atlas has a lot of mistakes in it. We used Netter's atlas, which is excellent. I still use it, you know, for the one or two tiny little vessels I can never seem to remember. As far as the review books, buy them now. That goes for all your classes. Buy one good Step 1 review book and read it before your tests. That will give you the condensed version before every test as well as help you tremendously when it comes time for Boards. Hope this helped. Good luck.
