Agree with what has been said about BRS Anatomy. You guys, however, didn't have the great Kyung Chung, PhD as your anatomy professor - at the University of Oklahoma, we did. BRS couldn't be an official class textbook - that's not allowed when the professor is the author - but it was all we ever used. At least when Chung was your anatomy professor, you knew that, if you could work the questions at the end of each chapter of Chung's BRS Anatomy, you'd do well on the exam.
Only thing about Chung is that apparently Korean does not have gender-specific pronouns. He couldn't understand why we were so upset that a question asking, "what is wrong with HER" had a correct answer of "testicular artery." Some of these errors (and some others) were missed by the proofreaders in the latest edition - but Chung's BRS is still the most compressed and thorough (and boring) read that you'll find.
Chung had students do most of the illustrations, and they're beyond horrible. Don't use them. I used to read Chung's and make cross-references in the margins to the appropriate Netter plate.
Your class is probably using Moore's. Don't get me wrong, I like Moore's (it was the official text for our class) and it's very thorough, but there was no way I could read it and ever be caught-up. I gave up in the first block after I got myself into serious trouble by getting so far behind. Great book, but there is not enough time to read it. Don't even try.
