Hi Lolz,
The good news is that leaving a SA is not the end of the world and you do have other options. The bad news is that the other paths to commission are now even more challenging/competitive for you. As Pima and others have said, getting ANY rotc scholarship right now is tight given all of the cuts that are happening. So here are some options to consider...
Sideload-type ROTC scholarships - Basically means going to college on your own dime and joining ROTC as a non-scholarship cadet. Then after re-proving yourself academically and militarily, apply for a ROTC scholarship. It's competitive, but impress your unit with your work ethic, grades, etc and make yourself the guy they have to have.
Join the Guard/Air Guard - This still remains perhaps the "best deal" out there! Because the Guard has both a state and federal role, you qualify for a variety of benefits. As an SA cadet you clearly have an impressive resume and should crush the ASVAB test (which you can prep for even more of course). Here is an example I know of...
As recently as last month there was someone who left an SA and joined Air Guard and got the following:
* 100% Paid tuition at any of the State Schools (varies by state)
* Choice of guaranteed jobs/bases
* 15k signing bonus (prior-enlisted from time at SA), paid after completion of Tech School
* Eligible for both GI Bill and GI Bill Kicker so along with Drill Pay they will be recieving roughly $950/month for the three years they are in school
* Excused from BMT as they had attended BCT at an SA
* Entered as an E3 due to prior time at an SA
* Can commission through the Guard far more reliably than through the AD OCS process
And of course all of this for one weekend a month plus two weeks a year (not counting Tech School). Crazy good opportunity for sure!
The downside? If you were set on going AD, then the path IS harder as you must transfer from Guard to AD based on the needs of the branch. In other words, if your MOS/AFSC is not what they need at the time.... good luck.
In any case, you do still have options so don't give up on your desire to serve!
