APUSH SHOWDOWN - Which prep book did the best?

<p>The AMSCO book is actually a little thick, but small in size. However, it is indeed a review book, and an excellent one at that. A very good supplement to the textbook, it helps break down topics very well.
I don’t think I actually found it on sale at a retailer, so I just resorted to Ebay. Try a search there!</p>
