While studying for the Biochemistry GREs, my good friend Anthony and I put together a number of study guides in LaTeX. Although we never finalized them (or checked them for error, really) and really only Anthony went down the grad school route, we were quite proud of them and, as such, are making them available for download.
Caution: the files are fairly large and neither Anthony nor I can make any assurances/guarantees of accuracy & quality
