The scholarship says up to 18K FOR tuition for a Type 7, so they may say he used 0, this yr., it is not a per se 18K merit scholarship. They do not cut you a check back whether you use 0 or you use 17,999. The key words are UP TO. As Thompson stated they will pay for your books UP TO, and you will get your monthly stipend. Remember the stipend is not yr round as a 100 or 200. So come summer time you will need to get a job if you want more money.
I would look into your school merit award to see how it is written EXACTLY. Does it say tuition for 4 yrs or does it say, X amount and knowing the cost currently, you divided it by 4 and that in your mind equals full tuition for four yrs.
EX: Our DS back in 07 for the 08 school yr. It stated 96K over 4 yrs. We did the math and woo hoo free ride.
He did not attend there, but 2 yrs later our DD applied and she got 115K. Did the math again and that is when we realized if our DS had attended, his AFROTC scholarship would have already kicked in because by 09/10. The cost to attend was 5K more per yr. than it was when he got his merit packet in 07/08
That is what you need to take into account. AFROTC will never cut you a check, but if the school is a monetary number with a limit that may matter in a yr or two.
I would also contact the college FA personally to see what they will do in your case. For example, if they place 18K from AFROTC (assuming tuition is 18K), will the school cut you a check back, thus you can use it for board. This is insanely rare, I have read it happening a couple of times, but that is out of hundreds of posters. Chances are not good, but again, you are still early enough in the process that they may change the package to make it a flat fee and that means you could use it for board. Win-win. Lower merit for them to pay out, and you get a full ride for everything.
Finally, as I have said it a million times. AFROTC scholarship is truly only guaranteed for 2 yrs. Scholarships are blind (masked) for SFT your 200 yr. If you don't get SFT, they can and most likely will dis-enroll you.
To feel confident that it won't happen, don't follow the 2.5 cgpa guideline. If you are non-tech you need a 3.3/3.4, tech 3.0/3.1 to feel safe. That 2.5 cgpa is not a true perspective when it comes to keeping your scholarship for 4 yrs.
Hope that helps.
OBTW AFROTC has not upped their Type 2/7 amounts since 09. In this current fiscal economy, I would not expect them to up anytime soon. Colleges on the other hand will usually increase at least 5%, many of them closer to 10% per yr. If that 18K is covering you to the penny this yr. according to their 12/13 rates expect next yr when you are charged, you will be short by a couple of grand. Our DD at VT IS has seen her rates go up @5K since you was accepted in Feb 10.
Apply for FAFSA just in case.
