Improve my writing score

<p>So The last Time I took the SAT(in may) I got a 660 on the writing. I missed 5 on the multiple choice and got an 8 on the essay. What would be the best way for me to improve my writing score? Should I focus more on grammar for the multiple choice or more on sat essay writing for the essay? I am aiming for 750+. I understand that Meltzer's grammar book is best for the multiple choice writing, but I saw the book, and it seemed quite large. It doesn't see, worthwhile to read through the entire book to get an extra 5 questions right. Are there any other resources? Also for the essay, I heard a lot of people on college confidential recommend pre-researching and pre-writing essays, and creating examples to prepare for essays How does this even work? There are like an infinite amount of types of essays, and there are infinitely many examples necessary to prepare for all the essays. Do people really do that? How does it work?</p>
