Depending on what books you have, you may want to revisit it anyway for prep and after step 2. I often open up my pathoma/goljan book, I have used BRS physiology more during 4th year than i ever imagined, still read a lot from the "clinic x made ridiculously simple" stuff, etc. I wish i still had access to the pathoma videos. i used first aid for my psych shelf, but i have never touched it again, so that book is largely worthless in my mind.
