Fleet processor said a change of desginator is not enough to resubmit. ( I asked about a month ago) You have to have significant change. For example, a new good LOR (from employer/prof or the like, no "buddies", Interview, new ASTB, GPA increase over .1, new job, significant increase in amount of volunteer/extra currics, finished/started MA,etc. Big things. If you had one of those, or more, you can resumbit before the 6 months.
For example, and all though I techincally do not have a resumbit cause it wasn't looked at in July, my new package now contains a GPA increase from 3.35 to 3.49, increased langauge skills, 2 new leadership positions on campus, new locations and more volunteer hours, new school activities (model UN, french club, and Tae Kwon Do), 2 new officer interviews (1 intel and 1 swo/sna), really good new prof LOR(didnt have an academic one prior)
From people in the community(intel) number one thing is to continue to improve, so work on things you enjoy and not just things for your packet
Good luck to everyone and heres to hoping for results before t-day!
