Work out. The rest you will learn in UPT.  Being physically fit will help, and you can work on that now.   (...and do well in academics and extra-curriculars so you can get into the programs you want.)

As a pilot, loadmaster, or crew chief? Loadmaster and crew chief: enlist and make sure you get the right AFSC to do that. Pilot: go the the Academy, do AFROTC, or go to OTS and get a pilot slot after completing the commissioning program.

Your school might have a cross-town agreement with another college's ROTC program.  If not, investigate OTS (which is after graduation). If you do not get a pilot slot, you would have to choose something else and fulfill your commitment in another job.  It's always good to have a back-up choice. AFROTC is a commissioning program, NOT an

I don't know if Dartmouth has ROTC programs.  If you have AFROTC, look into that.  AFROTC commissions about 1300 people per year, with about 500 available pilot slots.  If you join AFROTC, make sure you get good grades, do well on PT tests, and get a good commander's review.  Pilot slots are competitive, so the higher you rank ...

You can transfer to a 4 year college and do AFROTC, or you can get your degree and go OTS, or you can do the whole ANG thing (which I don't know much about) Basically, you should go for a technical degree (the Air Force likes them a lot more than non-technical degrees).  If you go enlisted, you might have trouble finishing your degree ...

I had a 3.95 GPA, a 34 ACT score, was an Eagle Scout (and a very active leader in my troop), Captained the Knowledge Bowl team at my school, played tennis, volunteered at my church, and did a few other little things.  My academics made up for my weakness in athletics, so I still made it into the academy.

Because I have some experience and a few connections, and because there aren't many other active posters here with USAF info.

I am a second year cadet at USAFA.

Like I said earlier, pilot slots are competitive and there are usually more people that want them than actually qualify.  So, unless several hundred pilot wannabe's droped out, no. The ''needs of the Air Force'' reign supreme though.  If the AF decides that they NEED everyone qualified to be a pilot, guess what...  That is NOT ...

Join AFROTC, get good grades, do well within the ROTC unit, and stay fit.  Once you can choose your AFSC, pick pilot!  If you have done well in college and ROTC, are medically qualified, and get a pilot slot, do well at UPT.  UPT is where you will track select (heavy, fighter/bomber, helo, etc.)  After you do that, you will go ...
