Hi aditiagg,
I'm sorry to hear that Test Day did not turn out better. From what you describe, it sounds as though you were essentially trying to self-teach the material - and while you scored reasonably well (the Average Score on the Official GMAT hovers around 550 most years - so scores in the low-600s are clearly above-average), you'll need to make some significant improvements to how you 'see' (and respond to) the overall Exam to hit a 720+. Thankfully, the GMAT is a consistent, predictable Exam, so you CAN train to score at a higher level.
From your posts, it also sounds as though you're only interested in applying to some highly-competitive Schools (even if you do not have an official list of Schools yet). As such, 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 act on that advice, the better). There's a Forum full of those Experts here:
https://gmatclub.com/forum/ask-admissio ... tants-124/Before I can offer you any additional advice for your studies, it would help if you could provide a bit more information on your prior studies:
1) What were your Quant and Verbal Scaled Scores on the Official GMAT?
2) How many hours did you typically study each week?
3) On what dates (or approximate dates) did you take EACH of your CATs/mocks and how did you score on EACH (including the Quant and Verbal Scaled Scores for EACH)?
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.
GMAT assassins aren't born, they're made,
