CR & WR Improving books

<p>I’ve read a lot of threads out there about many books, and it all came down to these.</p>

<p>Grammatix/Black book by Mike Barrett
Rocket Review Revolution
Barron’s Writing Work Book</p>

<p>I’m currently scoring 700~730 in both CR and WR when I’m good.
I want to push my scores up to late 700s.</p>

<p>Which of these books suit best for people in my score range?</p>

<p>I know CCers are out there who can give me great advice! </p>
