Best AP Lang. MC prep book?

<p>According to my teacher, the best MC preparation book is by [DS</a> Marketing](<a href=“http://www.dsmarketing.com/books_englishlang.html]DS”>AP Test Prep | AP Study Guides | D&S Marketing).</p>

<p>This is the book that my class uses and my MC scores have really improved. However, I do own PR and REA AP English Lang & Comp Crash Course but I wouldn’t recommend REA for MC. More for an overview of the class.</p>
