I'm not sure if they bumped Unsponsored age cutoff up with the general UPT cutoff age (from 30 to 33), but I thought it was 28.. So, if not, you might be a little late to grab one of those. My .02 from the few Unsponsored dudes I know here at UPT is that it's not terrible. One got picked up before even starting UPT and the others are still in the hunt. You'll be likely shunted into T1s and leaving fighters a very long shot, but it's not impossible if you get picked up. I wouldn't rule it out if it's an option. They need meat in the seats, so my brief time on base at UPT hasn't had anyone dropping drones. But, that can always change.
You have a good explanation for the college scores, but you might have to overcome the AFOQT scores, too. Your pilot is strong, and your PCSM is decent for heavies (fighters will be a stretch, I'd guess), but the other scores might on the low side for a lot of boards. I had a low Quant, so they can definitely be overcome, but you've got a few that aren't helping much.
In the end, it depends on how bad you want to fly mil, no matter the airframe, or if you're set on a certain mission. Keep networking and making friends in the community; that'll help, too! Good luck!
