<p>If you are really committed, then buy an AP Biology textbook and skim over concepts.</p>
<p>Also keep in mind that there's no "magical prep book" that will get you over the 700 mark. Just like there's no magical "diet pill" that can melt off your body fat without killing you, raising your score over 700 takes understanding. </p>
<p>But like I said, a good AP textbook should do.</p>
