Hi harvardforsure,
To start, planning ahead for when you should schedule your GMAT is a very pro-active choice - and that's great. However, you might not need all of that study time, meaning that you if you pay to schedule your Exam this far in advance, then you might end up having to spend more money to move that Test Date to an earlier date (when you are scoring at-or-near your Goal Score).
Back in early November, you posted that you had scored 650 on your first CAT/mock (without any prep). I'd like to know a bit more about how you have been studying since then:
1) What type of study routine have you been following? How many hours do you typically study each week?
2) What study materials have you used so far?
3) Have you taken any additional CATs/mocks? 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)?
4) Is your Score Goal still 730+?
GMAT assassins aren't born, they're made,
