Self-Studying APs?

I’m self-studying for the three AP tests Microeconomics, World History, and US Government and Politics to take the tests this May. I know it’s pretty early to be asking about this, but I don’t like procrastinating.
Right now, I’m just planning on using the Princeton Review books for World History and US Government, but I looked at the Princeton Review AP Economics book, and it didn’t looks very nice.
Any feedback? Any alternative preparatory books to use?
By the way, I’m not going into this situation blind – last year I self-studied 3 APs and passed them all, and I used Princeton Review for all of them, so I know that Princeton Review works most of the time.
Any comments greatly appreciated. Thanks in advance.</p>

<p>You should definitely watch the Crash Course videos for World History. I took the class in school as a HS freshman, it was extremely dense and difficult. How I got a 4 on the exam, I have no idea. </p>

<p>I don’t know about the Princeton Review, but I really understood the Barron’s WH, especially with each time period having a list of central themes. That was KEY to passing.</p>

<p>Last year I took WHAP and in all honesty it is completely possible to get a 5 with that book self-studying. I was in the class and took notes out of the textbook and all, but things didn’t really consolidate until the last 2 weeks of the exam and I felt more confident than ever. The 2 practice tests in the Princeton books are worth the go, but 200% harder than the actual test, therefore I suggest getting the 500 Practice Q book from 5 Steps. The questions on the new test aren’t as straightforward (more analysis) as those in the book, but it’s a super useful review and it has answers with explanations.</p>

<p>The thing that helped me the most on the test was learning dates. It saved me, honestly, because I wrote a terrible DBQ.</p>

<p>I know Crash Course has done wonders also, 4s and 5s for the high achievers since my school has a sucky Govt. teacher.</p>
