Hi Kinglucktsui,
While some people who took the At-home GMAT reported some significant 'wait-times' for their Official results (in some cases, several weeks), most people who have recently taken the At-home GMAT received their Scores within a week (sometimes as quickly as a couple of days). Once you receive your Score, you should post back here and we can discuss the results.
In the meantime, it would help to know a bit more about your timeline and goals:
1) What is your overall goal score?
2) When are you planning to apply to Business School?
3) What Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
