Hi Mandy001,
To start, since you are interested in some highly-competitive Schools, you would likely find it beneficial to speak with an Admissions Expert about your overall profile and plans. Those Experts should be able to answer your Admissions questions and help define the specific areas of your profile that could use some improvement (and the more time that you have to implement that advice, the better). There's a Forum full of those Experts here:
https://gmatclub.com/forum/ask-admissio ... tants-124/Many GMATers spend 3 months (or more) of consistent study time before they hit their 'peak' scores, so if you have studied for just 4 weeks - and you are planning to study for just 9 weeks in total - then there might be a limit to how much you can improve in that time. You're still performing at a relatively high level at this point (the Average Score on the Official GMAT hovers around 550 most years), but you might end up needing more training time than you have currently allotted.
As an aside, the 750+ score is approximately the 98th percentile - meaning that most GMATers never score that high on the Official Exam. Thankfully, NO Business School actually requires that you score that high - so it's important to realize that the score that you "want" and the score that you "need" to get into your first-choice School are not the same thing.
1) Are you planning to take the At-home GMAT or are you planning to take your GMAT at a Test Facility?
2) Going forward, how many hours do you think you can consistently study each week?
GMAT assassins aren't born, they're made,
