<p>This may I took 6 AP tests of which 3 were self studied: Environmental Science, Macroeconomics, and Microeconomics.</p>
<p>Much like many of you, I spent a lot of time reading the forums of which are easiest to self study and which books to use.</p>
<p>So heres my story:</p>
<p>AP ES: I used both Barrons and Smartypants. Started studying end of March.</p>
<p>Let me tell you-- this is a seriously easy test. If you study, you will get a five. If you know Smartypants front and back in detail, you will get a five. People say Smartypants doesn't cover everything, and that is true but you, combined with common sense, will know at least 90% of the questions on both MC and FRQ because ES is so much based on just simple logic. </p>
<p>BARRONS IS TERRIBLE AND AWFUL. IT IS WAAAY TOO DIFFICULT AND POLLUTES YOUR MIND WITH INFORMATION. It may be useful for skimming. The practice tests in Barrons are waaay too difficult too. For ES, unlike say physics, too difficult is a bad thing because you get so much information in your head that you start messing up other details.</p>
<p>Anyways just get Smartypants and study that hard and if you are interested skim through Barrons and you will get a 5</p>
<p>AP Economics: I used Princeton and Baumol's textbooks. Start studying around January. Didn't really focus on it until early April</p>
<p>Princeton is super condensed and short. If you don't read it twice you'll miss some details and if you have no background in econ you'll probably have difficulty learning only from Princeton. Econ itself is actually quite simple. Some people have a disposition towards it and others dont, but if you do reading a econ textbooks will make tremendous amounts of common sense and in the end the AP tests will be super easy. Each econ has a lot less material than most AP's so it is good for self studying. The Princeton practice tests are pretty realistic. You'll think they're too easy but really thats how difficult the test questions are. </p>
<p>AP Psychology: I ended up not taking this but I started studying for it in Barrons. I stopped because I realized Psych is just a lot of memorization, something that I suck at. The book was pretty thin and the test is only two hours. If you're one who is good at remembering what you've read then take AP Psych, it'll be easy for you.</p>
<p>Good luck. Remember: AP ES is, by far, the easiest AP I've taken out of my 8. I actually fell asleep during the test administration, twice.</p>
