<p>I went from a 620 to an 800 with a month of active prep.</p>
<p>This is what I did:
-Read Silverturtle’s guide. You don’t need to memorize it, but you should get a good sense of the grammar rules that you will need to apply on the SAT.
-Take the tests in the blue book. Make sure you review each and every question.
-Take 6 tests from the Collegeboard Online Course</p>
<p>That’s basically all I did. If you are an active reader of semi-challenging books you should already have a good idea about grammar. The writing section is not really that hard. It’s mainly about staying focused on the sentences and becoming a proofreading machine.</p>
<p>Most important thing, however, is that you only use Collegeboard material. The material from third-party books, in my opinion, is horrible (atleast the ones I have seen). Save yourself the trouble and stick to the BB/Online Course, and utilize each and every test to the max.</p>
<p>I used The Ultimate Guide to SAT Grammar by Erica Meltzer and it took me from a 680 to an 800. There is not a stone unturned about the Writing section in that book. She has massive amounts of exercises in there too. Helped. All of it. Plus I must have had good luck that day.</p>
<p>But highly recommend that book and her blog too.</p>
<p>I got a 790 on writing (missed 1 mc, <em>sigh</em> essay…)so i guess I am a bit below par to the people you are asking ^^</p>
<p>There is this nifty little Princeton review guide book that JUST has grammar. I think it is called “grammar smart”. I have never seen it sold in a book store, but I borrowed mine from a friend. I think it is amazing, and it explains everything in terms that anyone can understand. I adore that little book. I think it is a bit old too, so maybe a tour to Amazon can help you find it. </p>
<p>I would read Silverturtle’s guide and then do all the writing practice questions offered by Collegeboard. Review your mistakes, learn the new rules, etc. Good luck. </p>
