AP Chem Prep Books

<p>For those that are knowledgeable, how much more difficult or easier are the barrons and/or princeton review multiple choice questions compared to the real MC portion of the ap exam...i get 45 right on barrons and about 60 on princeton review. which is closest to actual test? thanks for your input</p>

<p>don't know about barron's, but princeton review is MUCH easier...</p>

<p>Barrons is unbelievably idiotic. Dont trust Kaplan either.</p>

<p>Barrons has too much information and a lot of it isnt even featured in the exam.</p>

<p>Kaplan thinks they're really smart and literally sucks at Practice Test. Question number 4 in Free Response is Chemical Reactions. The AP Exam states to assume that ALL reactions happen. However the Kaplan Practice tests reactions may or may not happen. How Idiotic.</p>

<p>Princeton is pretty good.</p>
