Hi Amiraa,
Many Test Takers spend 3 months (or more) of consistent study time before they hit their 'peak' scores, but it sounds like your studies were 'inconsistent.' Now that you've taken the Official GMAT, you can use that experience to better help you to prepare for your next attempt. Raising a 570 to a 700+ will likely require at least another 3 months of consistent, guided study though - and you'll have to make significant improvements to how you handle BOTH the Quant and Verbal sections. Thankfully, the GMAT is a consistent, predictable Exam, so you CAN train to score at a higher level.
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:
1) How have you scored on EACH of your practice CATs (including the Quant and Verbal Scaled Scores for EACH)?
2) When are you planning to apply to Business School?
3) What Schools are you planning to apply to?
4) Going forward, how many hours do you think you can consistently study each week?
GMAT assassins aren't born, they're made,
