Hi saishreesingal,
Before I can offer you the 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) Since you restarted your studies, how many hours do you typically study each week?
2) What study materials have you used over the course of ALL of your studies?
3) Which 'brands' of CATs/mocks did you use before taking your first Official GMAT?
Goals:
4) What is your overall goal score?
5) When are you planning to take the GMAT?
6) When are you planning to apply to Business School and what Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
