<p>i decided to take sat bio in october... so any advice? should i just memorize stuff in kaplan, princeton review and barrons?</p>
<p>No.
That’s really bad. I suggest taking as many tests as possible/doing as many questions as possible.
If you had half a decent teacher in 9th or in AP, then you’re ok (you know most of the material minus 3-4 topics like me). You should focus your energies on those weak spots, but I cannot stress enough the importance of taking tests. </p>
<p>Another thing, I recommend Princeton, personally I didn’t study for my June one, but Princeton seemed to have the most accurate practice tests (in comparison to the real one).
2. Don’t overkill yourself memorizing everything in Barron’s. Yes you will be overprepared, but if you don’t memorize everything you might end up memorizing small insignificant things like me. I felt that Barron’s overemphasized certain topics so I made sure to memorize those, but on my Oct test, well those topics weren’t covered. 
</p>
<p>Kaplan. Had a lot of wrong answers. You might have to cross reference a lot or know what you’re doing because you may get very confused. </p>
<p>PR editions 2007-2010 are all identical. Don’t break a leg trying to find the 2009-2010 in fact the 2007 is nice and color coded lol. Remember to check the library first. I’m proud to say I spent only 18.50 on my latest round of SAT Subj prep books. </p>
<p>btw you can pm me if you have any content related q’s to keep me on my toes.
Best of luck to you.</p>
