<p>If I'm self-studying AP environmental is it necessary that I get a text book?</p>
<p>I bought the PR book and am currently taking AP bio. My teacher said that anyone who is doing well in AP bio could get a 5 on the APES if they studied a bit. </p>
<p>I'm pretty decent at taking tests (5s on AP Calc AB, APUSH, and AP English Lang last year) and am doing really well in AP bio (and I got an 800 on the bio M SAT II), but I also haven't really studied much yet. I've read a bit of the PR book but my schedule has been pretty busy so I haven't had much time. Do I need to be worried at all? Should I start studying right away?</p>
<p>Thanks in advance.</p>
