Self-Studying AP Biology?

<p>I'm a rising junior, and my school won't let me take AP Bio because I only got an 85 in Freshman year bio (I didn't pay much attention Freshman year). So I was thinking about self studying it using the Campbell's book. How hard is it? If I start prepping this summer, do you think I could take the AP Exam next May?</p>

<p>If you study for a whole year, then I assume you’ll be fine. That would be so much time reviewing materials…</p>
