SDN Members don't see this ad. (About Ads) Did well in basic sciences, didn't use other resources because all of the info that you need is in FA/Uworld. They certainly explain it in enough depth and the key is UNDERSTANDING everything in those texts. That being said, I looked up tricky concepts on wiki which I honestly think is a better use of time than additional textbooks. Too much verbiage in those books, you need to have TWO resources max and know them cold.
