Bio and Math prep over the summer?

<p>I plan on taking the SAT II's in Bio and Math (undecided which one, most likely math II though).
I have only taken basic bio courses, not AP. But I'm generally good as science and I like bio so yeah.
Anyway, what are the best books to buy to prepare for these two tests over the summer?
I only really have one chance, because I may apply ED.
Thanks in advance.</p>

<p>For Bio, Barron’s and Princeton Review used together is the best combo. I memorized from Barron’s (it has nice charts/tables), then read Princeton Review through quickly. Some of the questions were actually straight from Princeton Review (maybe 2 questions), so skimming Princeton Review was worthwhile. Hope it goes well.</p>

<p>^ How did you do?
And any tips for math?
Is math II a LOT better than math I because I’m much more confident about the things covered in math I.</p>

<p>For Math Level 2, I used Barron’s for the facts and practice and I used CB for the realistic practice tests and Sparknotes for more practice.
(I got an 800)</p>

<p>I got 680 my first time, 700 my next time, and hopefully 750+ this last time (scores haven’t come out yet). Memorization is key.</p>
