<p>Self-study whatever you want, as long as you have the time (which may range from a couple days to the school year). But be aware that many selective colleges don’t offer credit for Human Geography or Environmental Science. Contact your AP coordinator (or counselor if they’re the same person) first, and if you can’t get them to order an AP exam for you, contact CollegeBoard. I think they can find you contact information for AP coordinators at nearby schools.</p>
<p>For some (if not all) subjects, you can rely solely on the prep book and past FRQs provided by CB on [AP</a> Central](<a href=“Supporting Students from Day One to Exam Day – AP Central | College Board”>Supporting Students from Day One to Exam Day – AP Central | College Board). This worked for me on Psych, Comp Sci, Physics C: E&M, and Lang (yes, I self-studied all of those), so I’m guessing that this should work for whatever you want to self-study. You can also use a textbook if you want to go more in-depth or get more practice problems, etc. but if you’re short on time, a prep book will usually suffice. (I heard APES was pretty challenging this year, though…)</p>
