I'm just curious, does Princeton Review MCAT Biological Sciences Review= Princeton Review Hyperlearning?, or is "hyperlearning" a different series in and of itself, because I have heard of nothing but praise for hyperlearning.
It's the Biological Sciences book from their Hyperlearning course - so yes, it's the right book.
There is a PR MCAT book (with all subjects covered) that you can buy from bookstores and then there are the TPR Hyperlearning books that you can only get from the course - or 2nd hand off classifieds/eBay.
