I was told by a 4th year that Iserson's Guide to Residency was a great book to get and a must have when applying for residency programs. However, I sat in Barnes and Nobles and looked through the book and I decided that it was too many pages and not worth buying. And if I needed to read it I decided that I would just go Barnes and Noble and read the sections I needed to read. Instead I bought First Aid for the Match. My question is what are everyone's thoughts on these kinds of guides to getting into residencies and matching. Should I go to the store and buy Iserson's too? Any preference between First Aid and Isersons? Any parts of either books that you found absolutely necessary. I'd appreciate everyone's thoughts.
