Best SAT Grammar Book (For one who already knows grammar)

<p>Does anyone have a grammar book suggestion for me? I'm already quite proficient with grammar (usually score -3,-2 wrong), but I always find that there is some question that I' not sure with.</p>

<p>I bought the Grubers book, but they insist on going over prepositions and verb tense (all that I already know). Anyone have a suggestion to a book that will cover the more tricky parts of the SAT, the parts that usually stumps people :</p>

<p>Ex.</p>

<p>The error between</p>

<p>tendency to come
tendency of coming</p>

<p>I'm really aiming for a high score on the November test, because Writing is the only subject where I consistently get lower scores (760-770).</p>

<p>Thanks!</p>

<p>Silverturtle’s guide covers the writing portion every thoroughly, and I have also read exerpts from Rocket Review that were very good.</p>

<p>Personally I used Manhattan GMAT Sentence Correction guide, and I’m pretty sure that I got 100% on MC yesterday, maybe -1. It covers all the same tested concepts and also contains a very thorough idiom list.</p>
