Hi ally510,
Studying for the GMAT now - years before you will actually 'need' your Score - is a smart choice. In this way, you'll have your Score 'locked up' and can focus on building the other aspects of your profile. Your Official GMAT Score is valid for up to 5 years, so as long as you apply before your Score has 'expired', you'll be all set.
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:
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) Do you have an exact Test Date yet (and if so, then when is it?)?
GMAT assassins aren't born, they're made,
