Hi Maumaxu,
Many GMATers spend 3 months (or more) of consistent study time before they hit their 'peak' scores, so if you've been studying for less than a month, then you shouldn't expect to have mastered any of the concepts just yet. In that same way, if you took your 1 practice CAT/mock in a way that didn't match-up with how you took your Official GMAT, then it's possible that that result was unrealistic and 'inflated.' Thankfully, the GMAT is a consistent, predictable Exam, so you CAN train to score at a higher level (and now that you've taken the Official GMAT, you know the exact details of Test Day, so you can incorporate them into your studies and be better prepared for your next attempt). With a Score Goal of 730+ though, you will likely have to make improvements to how you handle BOTH the Quant and Verbal sections.
Before I can offer you any additional advice for your studies, it would help if you could provide a bit more information on how you've been studying and your goals:
1) Over the last month, how many hours did you typically study each week?
2) What study materials have you used so far? What “brand” of CATs/mocks have you used?
3) When are you planning to apply to Business School and what Schools are you planning to apply to?
If you took your Official GMAT at a Test Center, then 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.
