Hi adityakhaire,
With a November 25th Test Date, you have less than 3 weeks of study time remaining. Raising a 630 to a 700+ in that time is possible, but it might be too challenging to be considered realistic. As such, you would likely find it beneficial to push back your Test Date so that you can continue studying.
Before I can offer you the additional specific advice that you’re looking for, it would help if you could provide a bit more information on how you've been studying and your goals:
Studies:
1) How long have you studied?
2) What materials have you used?
3) How have you scored on each of your CATs (including the Quant and Verbal Scaled Scores)?
4) Did you take the FULL CAT each time (with the Essay and IR sections)?
Goals:
5) When are you planning to apply to Business School?
6) What Schools are you planning to apply to?
