Hi hbcm21,
Since you're relatively early-on in your studies, spending money on a tutor might not be necessary at this point. With a 6-month study window, you've given yourself lots of potential study time - which is good (since many GMATers spend 3 months (or more) of consistent study time before they hit their 'peak' scores).
Have you taken any practice CATs/mocks yet? If you have, then how did you score? If not, then it would be a good idea to take a FULL-LENGTH practice CAT Test; you can take 2 for free at
www.mba.com (and they come with some additional practice materials). That score will give us a good sense of your natural strengths and weaknesses and will help provide a basis for comparison as you continue to study. A FULL CAT takes about 3.5 hours to complete, so make sure that you've set aside enough time to take it in one sitting. Once you have those scores, you should report back here and we can come up with a study plan.
Before I can offer you any additional advice for your studies, it would help if you could provide a bit more information on how you've been studying and your goals:
1) Since you're a full-time student, how many hours do you think you will be able to study for the GMAT each week?
2) What study materials do you currently have access to?
3) 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,
