Hi 5143kny,
I'm sorry to hear that Test Day did not go better. Not answering those 11 questions would certainly have impacted your Score a great deal. That having been said, even if the timer had popped up at the 1-minute mark in each section, you would have essentially have had to blindly guess on all of those questions anyway. This implies that your current approaches for those sections are inefficient - and if your Score Goal is a lot higher than this 570, then you'll have to make some 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 any advice for your studies 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? How many hours do you typically study each week?
2) What study materials have you used so far?
3) How have you scored on EACH of your CATs/mocks (including the Quant and Verbal Scaled Scores for EACH)?
Goals:
4) What is your goal score?
5) When are you planning to apply to Business School?
6) What Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
