<p>So which prep books are the best for the SAT II Biology E/M Test? I am using the McGraw Hill 2012 Third Edition book (only one at the library I found) and the Princeton Review AP Biology book to prepare for this exam. What are you using?</p>
<p>And how hard is this test? The AP Biology course at my school sucks and I basically had to self study the entire subject. And I did hear that the SATII for this is pretty difficult. Is it hard because there is a lot of detail? or do they ask you random questions? or…?</p>
