Is Barron's Overkill for Biology SAT 2?

<p>There seems to be a lot of overly detailed information in Barron's for the Biology SAT 2. Is this information just extremely thorough and worth studying, or is it actually too detailed and not geared towards the test enough?</p>

<p>Focus on Princeton’s. I did the SATII molecular Biology test in Jan. I studied Barron’s like heck, memorized all the phylums and *****, and there were experimental questions that I had no idea how to do because I skimmed over Princeton Review. Still didnt do badly, got 780. But I would have gotten 800 had it not been stupid Barrons messing with my head</p>
