Hi WhiteKnight8,
Studying for the GMAT now - far in advance of when you'll "need" your Score - is a smart choice. With this 700, you're actually closer to a 750+ than you probably realize, but you're going to have to make some fundamental changes to how you "see" (and respond to) BOTH the Quant and Verbal sections before you can get to the point that you can consistently score at that higher level.
GMAC has publicly stated that the Official Score that you earn on Test Day is within +/- 30 points of actual ability. Assuming a similar 'swing' in how your CATs function, your CAT score results - along with your Official Score - show that you essentially performed the same each time (about 700 +/- a few points). You handle certain aspects of the GMAT consistently well, but you also make certain consistent mistakes.
From what you've described, your studies so far have been "book heavy"; unfortunately, many GMATers who study in that way end up getting 'stuck' at a particular score level. Even the best books are limited in what they can teach you; they also can't force you to approach questions in a certain way and their explanations are often one-sided. As such, you would likely find it beneficial to invest in some new, non-book study materials for this next phase of your studies. In addition, while the most realistic CATs available are the 6 from GMAC, retaking a CAT that you've already taken is NOT a realistic way to assess your skills - since you will likely see some 'repeat' questions that you have already faced. Unfortunately, seeing even a couple of repeats can 'throw off' the Scoring Algorithm and impact your pacing, energy levels, fatigue, etc. (meaning that they would likely all appear to be better than they actually are). Thankfully, the CATs from Kaplan,
MGMAT and Veritas are all 'close enough' to the real thing that they will provide you with a relatively realistic score assessment (assuming that you correctly take the CAT in a realistic fashion) - so you can use CATs from any of those sources during this next phase of your studies.
1) Assuming that you would probably need another 1-2 months of consistent, guided study - going forward, how many hours do you think you can consistently study each week?
GMAT assassins aren't born, they're made,
