<p>i know doing the CB books help and grammatix has been said to help, but what other books are best for CR practice?</p>
<p>I heard Rocket Review is decent for the CR .</p>
<p>BB is the only thing you should use for CR practice. You can study strategies from other books, but only use official CB material for practice questions.</p>
<p>^ I agree. While Writing and Mathematics in the other books test pretty much on the same mathematical/grammatical concepts, the CR section is the most difficult to reproduce with accuracy because the vocab bank and passage topics/questions can vary A LOT.</p>
