wow i'm surprised at how many people advocate studying early. First aid is a mindless collection of facts. I don't see how it would at all help to study it early. In the first two years you have to actually learn the material, which I don't think you can do from the likes of BRS and HY. As I prepare for the boards, I see that the things I know well are largely because I happend to learn them well during school, from class notes, textbooks, and espeically seeing patients on the wards. The things I never learned because I slacked during those units (which is most things 🙁) are really hard to solidify from review books after the fact. One thing that might help is reading RR path during pathology since it is relatively extensive but a lot more manageable than robbins.
