<p>Hi, I haven't taken a class of Biology since Sophomore year. And it is now my senior year. I've been self studying SAT 2 Bio from the Princeton's Review, but I'm not sure if it's enough to score a 700+?</p>
<p>Should I devote my time to PR, or should I also study and practice from other books? I also heard that Barron's is quite difficult compared to the actual SAT 2 test.</p>
<p>In my opinion , kaplan barrons sparknotes etc are all good review guides to score 700+. You just have to effectively read the guides and take in all the information in the guide. </p>
<p>I used sparknotes’ guide which is free and I got a 780. Just pick a guide that you feel comfortable with and stick to it.</p>
<p>The current edition of Princeton Review is extremely comprehensive and really good for Bio. I wouldn’t look at Barron’s unless you have a lot of time because a lot of the information in Barron’s rarely ever shows up on the Bio SAT.</p>
