<p>I've heard time and time again that Math and Writing are the easiest sections to improve on because you can just prep for them. Everyone knows Barron's will help you with math and that Direct Hits will improve your CR. That leaves a question unanswered, what's the best way to prep for the writing section? Is there a prep book that will teach me all the rules I need to know in order to score a 750+?</p>
<p>Try Erica Meltzer’s Ultimate Guide to SAT Grammar. Hands down the best book I’ve found for the Writing section. Tons of practice questions and cross ref’d with BB so you can find the questions there too.</p>
