Hi definitelynotAmit,
Since you have a specific application plan in mind, 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/ A 620 is a strong initial CAT score (the Average Score on the Official GMAT hovers around 550 most years). Many GMATers spend 3 months (or more) of consistent study time before they hit their 'peak' scores, so you won't necessarily need a year to prepare for the Exam, although you will have to learn, practice and master some really specific Quant and Verbal skills before you will be able to consistently score at the 730+ level.
1) Since it sounds as though you will be a full-time student while you are studying for the GMAT, how many hours do you think you can consistently study for the GMAT each week?
GMAT assassins aren't born, they're made,
