<p>i would recommend either taking the course or ramping up the studying a lot. The AP Bio tests was one of the hardest I've taken, even with the class (and I've taken four without taking classes).</p>
<p>^^Sure, if you actually have the time to read through all of it. Preferably twice. You could probably just use Campbell and Princeton Review if you read Campbell <em>very</em> thoroughly, PR's not as good as Cliffs but one heck of a lot shorter.</p>
<p>Just read the entire Campbell textbook (~1000pages) and you should be good, I thought the AP Bio test was extremely easy (got a 5) but I had an awesome teacher.</p>
