SATII Prep Book Cramming suggestions

<p>I need some suggestions for SATII Math2C and SATII Biology prep books. These tests are in 3 weeks and i need to cram. I've heard Barrons is great for Math, but ive heard that its too long and difficult to start cramming now. Any suggestions?</p>

<p>i just bought the REA one for IIC. Looked good but havent worked thru it yet. 6 practice tests w/ explanations...plus i heard their tests are generally accurate. but maybe it isnt good havent worked thru it yet.</p>

<p>i thought itd be a good book for cramming too. =)</p>
