Hi RF1010,
Many Round 1 deadlines are in September (although individual Schools/Programs might have earlier options), so if you want to have your Official results banked before you apply, then you have to work backwards from those dates. You might also consider the possibility that you might need to retake the GMAT, which would require that you give yourself even more lead-time. Beyond those details, if you want to take the Exam on a specific day of the week and at a specific time, then you will likely need to plan far in advance and book a date early-on (since Test Centers are relatively small and can only accommodate a certain number of people at a time).
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? What “brands” of CATs/mocks have you used?
3) On what dates (or approximate 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) What Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
