First step is to go to your doctor and tell him or her that you need a shot of valium...😉
I don't really understand what your confusion is about, but I will let you know my preference for books. I actually preferred just about all of the BRS books over all of the other review books because they were well written and had practice questions at the end of every chapter. The BRS books that I would buy are pathology, physiology, and possibly behavioral medicine. High yield is alright, but I found most of their books more tedious to read cover to cover then the BRS books. High yield did have nice embrylology, biochemistry, and behavioral medicine books as well though.
