Sent an update to adcoms this Monday. They said they will reconsider the scholarship decision in adcoms meeting. They will inform me about the result next week.
Not sure about my odds to get scholarship, but at least I tried.
If the scholarship is merit-base only, don't expect b-schools to sympathize with you on your poor financial condition.
You'd better have some updated information after you got the admission, so that you can request a re-evaluation. Sending a short essay to talk about your recent developments would be a good idea. Talk about something new, something that you believe will contribute to the school.
