Hi 197369,
GMAC currently has an 8-attempt-at-the-GMAT limit per person (with no more than 5 attempts in any 12-month period) - that includes no more than 2 attempts at the At-home GMAT. Since you have already taken the At-home GMAT once already (in February), if you do not think that you have a realistic shot at hitting your Score Goal, then you should not 'rush in' to take your 2nd (and last) At-home GMAT too soon.
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 did you score on your 1st Official GMAT (including the Quant and Verbal Scaled Scores)?
2) How long have you studied in total? Over the last 3 months, how many hours did you typically study each week?
3) What study materials have you used over the course of ALL of your studies? What “brands” of CATs/mocks have you used?
4) 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:
5) What is your overall goal score?
6) 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,
