Hi Chrisb2345,
After scoring your original 680, did you ever end up applying to Business School? I ask because any prior application attempts could help you to better plan out your upcoming approach to the Round 2 applications. In addition, it's not clear whether additional tutoring is something that you "need" or not, so 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 for this recent attempt at the GMAT?
2) What study materials have you used so far?
3) How have you scored on each of your recent CATs (including the Quant and Verbal Scaled Scores for each)?
Goals:
4) What is your goal score?
5) When are you planning to retake the GMAT?
6) What Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
