<p>I'm currently studying with Princeton Review,
but i dont think its enough so i'm just going over
my school biology textbook (hella detailed).</p>
<p>But is going over whole biolgoy textbook helpful
on preparing SAT biology test?Or should i just
study with other sat books like Kaplan and Barrons?</p>
<p>I need all of your comments!</p>
<p>Don't read your textbook unless you feel like you need to clarifiy something in one of your study guides. Reading the textbook just wastes your time and effort unless you need it for a specific purpose. If you've taken something like AP Bio and have done well then you really just need Princeton Review. But if you want something extra then Kaplan and Barrons are both good choices (Barrons tends to over prepare you). If you've only taken freshmen Bio then I would suggest going through a few of these study guides. </p>
<p>Going through the Princeton Review and a few practice tests helps immensly.</p>
