<p>I have already browsed through the "Consolidated book suggestions for AP" thread, and have narrowed the list of AP prep books I want to buy. However, I have not narrowed it enough. Currently, I have the following:</p>

<p>First, I must note that I am not necessarily planning on taking all of these exams. But I am seeking recommendations for which books to remove from and add to my list. I have more than 2 books for each subject, but I would prefer only 2 books. Please take into consideration that the asterisks indicate self-study (if I were to take the exam). There are a few subjects where I have only a few books (1 or 2), but if anyone else feels I must have a certain book for that subject, please recommend! Thanks in advance.</p>
<p>Also, I acknowledge that prep books are not necessary for AP English Literature. I received a 5 on AP English Language without any prep books. However, I would like to be at least more prepared.</p>
