The first book I would highly recommend that I do not see in your pile is the PowerScore GMAT Sentence Correction Bible. This is a great book for doing well on the sentence correction. It has helped me a lot in refreshing my verbal skills.

Another book I would recommend is the Kaplan Mastery Practice (LSAT course book). This is great for CR. However, I was lucky enough to have a friend who had this book from taking Kaplan’s LSAT class and was finished with the book. The reason I recommend this is that the CR questions on the LSAT are far more difficult. The book has the different CR questions split all the way up to five star questions. On the GMAT you would only run into at the hardest a two star question in the Kaplan book. So what I did was I practiced out of the LSAT book and went all the way up. I just did make the transfer to GMAT type CR last week and I have been crushing them. If you cannot get your hands on the Kaplan course book maybe look into some other LSAT CR review books. Maybe you can find someone out there though that recently took a Kaplan class.

I cannot prove what I say with a score because I have not taken the GMAT myself either. I am also in search of the 700 level. I have been studying since May and am now just practicing time, etc. I have been meeting with a tutor and will be taking the test in the beginning of September. If all goes according to plan I will post on this site my detailed study plan since May.

Tip: become involved in this site, I have not had the chance but wish I had started way earlier. This is my first post actually. Hopefully more to come!
