Beat The GMAT a GMAT & MBA community

Hello,

I took the first GMAT exam in Sept 25th, and got a 640. About 2 months ago, I began studying for the exam again for an hr or so a day. This time, I've been using an excel sheet to track my incorrect and correct answers. I've done all 8 MGMAT guides. I've redone the OG 12th Edition. I've done CR Bible again. And I plan on taking my exam on May 25th, just before the change.

My question is, I've still got a month before my real exam, and I've completely run out of practice material. I will be taking the GMAT Practice Exam (1st Version) today, but I've taken it twice already before I took the real exam on Sept 25th. So obviously I will be seeing the same questions again.

Also, I've heard the GMAT prep 2.0 (with IR that came out recently) contains the same EXACT questions! So, is there a point in taking the new practice exam? I do plan on purchasing the question pack, that will give me 400 extra questions.

Other than just re-doing old GMAC questions (which i've heard is the gold standard for questions, because they create the same "feel" of the real exam), is there other practice material I should be looking into?

Oh, and another thing, before my first exam on sept 25th, I did the Princeton Review 2012. So I did all those practice questions too. Some people have suggested that I just keep re-doing OG questions over and over, and taking the GMAT Prep Exam over and over. Is this a good idea if I've already seen all the questions at least a couple times?

Considering the information I've given above, is there anything else you guys recommend that I look into and practice before my exam in May? THis will be my 2nd time taking the GMAT and I am aiming at 700. PLEASE PLEASE PLEASE HELP!!!
