<p>DON'T USE REA. Or don't use it very much. I am sure PR would be much better...I have REA (it is ALL I have because someone gave it to me for free to use)...and it isn't really AP style. I read the whole first section and it didn't help at all...then I went to class (we have a normal semester schedule) and we reviewed it in class from just our normal textbook and I remembered everything from the textbook and was happy.</p>
<p>My advice is 1.) Review your textbook (is there a shorter version of the textbook you used online or anything? Mine has these cool review summaries online) and 2.) Take at least one practise test before the actual test, 'cause that helps a lot. See if you can go back to your teacher and ask them for advise about the essays you did on the practise test.</p>
<p>I have never seen PR AP Euro, but PR is usually pretty good...That's why I am assuming it is better than REA, which just summarizes and (though it's got lots of nice practice tests) doesn't have questions or analyzing stuff after the review part.</p>
