Hi MaxVerbal,
Many GMATers spend 3 months (or more) of consistent study time before they hit their 'peak' scores, so if you're planning to study until August or September, then that gives you a LOT of potential study time (and you might not necessarily "need" a tutor to hit your Score Goal - as long as you are focused on learning and practicing the proper Tactics). At this point, before you invest a lot of time and money into any new GMAT resources, it would help if you could provide a bit more information on how you've been studying so far 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) On what dates did you take EACH of your CATs/mocks and how did you score on EACH (including the Quant and Verbal Scaled Scores for EACH)?
Goals:
4) What is your overall goal score?
5) 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,
