<p>I self-studied AP Euro as a sophomore, and got a 5. It was my first AP. BUT IT WAS A TON OF WORK. I did three timed essays per week, even during vacations (I wasn’t used to writing in a time limit,) studied numerous AP prep books, read everything I could about the test online, and (of course) read tons of books about European History. So, I did well, but I wouldn’t recommend the experience. (Although it did whip my writing and test-taking skills into shape.) Also, I am something of an academic masochist with free time–if you aren’t those things, you might not want to do this. (But if you are those things, more power to you I guess! :)</p>
