AP euro best review book for self study?

Which ones covers a lot of information and will help me pass the AP test? I only need a 3 (though a 5 would be nice to keep my straight 5 record so far), and I basically know 0 european history (taking it to clear a GE)</p>

I heard Crash course, Princeton review, and AP achiever are all good. If I were to thoroughly study cc and pr, would that be enough to get a 5? Should i do cc/pr or ap/pr</p>

information wise, Modern European History is awesome for cramming, but it won’t give you sample quizzes, tests, FRQs, etc.
PR is good for a test prep, and Crash Course is also good to review.</p>

Crash Course is very good. REA does have a practice test but I haven’t looked at it.</p>

The AP Achiever is my savior. Helped me get a 5.</p>

I hate to ask another question on this thread because it was originally about review books, but how much time should someone spend for self-study European history… can it be done in a summer and then reviewed again before the AP exam?</p>
