Larry Krieger has set up an APUSH Crash Course page on Facebook, and it’s a really impressive (not to mention free) resource.
In addition to posting full-length sample essays with paragraph-by-paragraph explanations of how to present key points, he’s made a number of videos walking students through the test as a whole, the long essay, and of course everyone’s favorite: the DBQ.
He even explains what you need to include to obtain specific scores.
Larry is truly the APUSH guru. He knows the test inside and out, and I strongly suggest that anyone taking the exam check out the page. Even if you’re already in good shape, you’ll probably pick up a few tips.
