I agree with what has been said.
Unfortunately, you have missed the ability to take the PSAT. You always want to take it for 2 reasons.
1. It gets you accustomed to the test
2. If you score in the 95% you are eligible to become a National Merit Semi-Finalist. This looks good on your resume. Colleges take note at that, especially when it comes to doling out merit packages.
~~~ Remember AFROTC will only pay tuition, and 95% of those scholarships are limited to no more than 18K. It makes going OOS or private a challenge.
Additionally, AFROTC does not superscore SAT or ACT. It is the best sitting. It is still advisable to take both exams and frequently, but just be aware it is best sitting.
As has been stated 30 is where you want to be to feel comfortable. I would say for SAT you want to be 1300, especially if you intend to go non-tech. They do not include your writing portion, or at least they didn't in the yrs past.
Academically, what concerns me is it appears you have no honors or APs. They will look at not only the cgpa, but the rigor of your curriculum. The sealed transcripts will include a school profile, and this will tell them if you had the ability to take Honors or APs. Some schools don't allow APs until SR. yr., if that is your case, you will be fine.
As far as ECs. AFROTC only looks at everything through your jr. yr in HS. Any position you have as a SR. will not be included. Some kids can find ways to get around it because they hold elections or appointments in the spring of the school yr for the next fall. For ex: you can say you were selected April of your JR. yr to be XYZ.
CAP works in your favor.
TKD is not considered a sport per se unless you are on a competition team. It is still a great EC, but staying with track will help in the points. The reason why this occurs is because they can't really tell the rigor of TKD, do you do it for fun, 2X a week, etc? Our DS did TKD, and they accepted as a sport since he competed on the state and national level.
The other reason to stick with track is they are looking for your commitment level. Do you stick with it, or do you give up because you were not the shining star. AFROTC is a commitment, and the best predictor of the future regarding a person is their past.
The fact is nobody here sits on the board. Nobody here will not the quality or the size of the application pool next yr. We can only show you where we see weaknesses and strengths in your profile with the limited amount of info you desire to share.
If you want to be chanced, the only chance I will give you is you have 0% chance if you don't apply. Every yr there are candidates that posters will say you look great, and others that are let down politely, yet a few short months later the let down ones get the scholarship and the look great doesn't. If the let down ones never applied, they would have lost the chance for a scholarship.
Finally, one big factor is your DoDMERB exam. Get those records in order now. Many kids get DQ'd and in today's climate, waivers are not as easy to come by as they were 5 yrs ago. It is silly things that they never thought would impact them, such as vision, allergies (food), or medication given over an extended period. I would say at least 2 or 3 every yr have had an inhaler prescribed when they were 14 or older, never used it, but it is still on their records with annotation of asthma...when it was just a bronchial infection, but to DoDMERB your doc said it was asthma, and now they will take that path.
Good luck.
