Hi SB0895,
I'm sorry to hear that your recent attempt did not go as well as hoped. Based on what you have described, there are a couple of factors that might be negatively impacting your studies at this point. First, 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. Second, 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).
The 740+ Score is approximately the 97th percentile, so clearly most GMATers won't score that high on the Official Exam. Based on your recent Official Score, you clearly have the opportunity to pick up significant points in BOTH the Quant and Verbal sections. While there's no way to know for sure what YOUR potential best GMAT Score might be, I'm pretty sure that you have not gotten to that level yet.
it would help if you could provide a bit more information on how you've been studying and your goals:
1) How long have you studied in total? How many hours do you typically study each week?
2) When are you planning to apply to Business School?
3) What Schools are you planning to apply to?
You might also choose to purchase the Enhanced Score Report. While the ESR doesn’t provide a lot of information, there are usually a few data points that we can use to define what went wrong on Test Day (and what you should work on to score higher). If you purchase the ESR, then I'll be happy to analyze it for you.
GMAT assassins aren't born, they're made,
