<p>I'm a senior taking a few AP classes this year. I got an A in all except Bio, got a B there. The thing is though, my first test in Bio I got an 83, and by the end of the quarter my test grades were 96 and 100 (but the labs brought me down ugh.) But that's an easy fix, all I have to do is look over those and follow guidelines. In Econ though...I get the exact same grade every single test...80, 80, 80, 80. I've looked over my previous tests and notes, but it doesn't seem like enough. I was thinking about getting a book study guide book, because that's what's working for me in Bio. The questions I tend to get wrong are the ones on the FRQ and slightly skewed application questions on the scantron. Anyone have any good sites or books anyone could recommend for me? The monopolistic competition, game theory, and oligopoly test is coming up and I want to make sharp change. Thanks in advance!</p>
<p>Definitely get a guide for the AP exam and use it for the class. The Princeton Review one worked for me (get an old version for cheap or something).</p>
