I agree with mkoch.
RockyMtn, first off I am glad to see you on here again, it has been a long time since I have heard from you.
Second, what kind of changes apply to part 4c. Like I said above "i.e. several major volunteer positions, some new LOR's - one from a congress person, revamped my resume, joined some more professional clubs, ran a competitive 5k and 10k, etc. over past 4 or 5 months since I first submitted". More specific for the volunteer positions, I was a Team Captain as well as on the Logistics Committee for a brand new Relay For Life event for the American Cancer Society in East Boulder County (the event just happened last weekend and went wonderfully, money-wise we blew our goals out of the water - Team goal was originally $1000 and we raised over $2000, Relay overall goal was $30,000 and we raised over $40,000). That is just one of the specifics on things I have done over the past 5 months or so to better myself and change my application. If this is not qualifying, in addition to the letter of reconsideration, which I already wrote and turned into my recruiter with the rest of the package, then I don't know if I understand what else could be changed. Besides maybe like mkoch said about GPA while still in school, or maybe retaking the ASTB (which if I did I would risk lowering my already decent score), or something else major that would happen in a small amount of time as six months is.
I appreciate all your responses, thank you all. I appreciate you coming back on to give some input on here RockyMtn. Any clarification or thoughts on if I qualify to resubmit or not would be great. It honestly sounds like it is fairly open to interpretation on what makes one "more qualified" that would be any different with another 6 (or 4 from now) months. Ok, enough of me rambling...
Edit: Oh, and Sirenia, I am only at the Pro-rec stage, trying to get a pro-rec from the Intel board. I have only just started!
