<p>If you want to know how long the textbook is, can’t you search amazon? O.O</p>
<p>Are you kidding me? You have NOTHING else to do? Like getting a job or trying to find a research placement (if you want to go into anything sciency)? Or studying for Math contests?</p>
<p>European History, I would really recommend AP achiever, it is not a dull book like most (particularly Modern European History, which is possibly the dullest book I have ever read.) It has about 300 pages of textbook like (only more interesting) material, including practice questions at the end of each chapter. It also gives good advice on writing the essays, and has a lot of sample essays with comments on why that essay got the score it did (one at the end of each chapter, and 8 for each of the practice tests at the end, 2 DBQ samples and one for each FRQ). The 2 practice tests are excellent. It took me (very rough estimate) about 125 hours total to prepare for European History.</p>
