Well, I am sorry to hear that - but glad you see the end goal!
Well, here's a question for you to answer yourself: What do you want to do after commissioning? Do you want to go AD? or Reserve/Guard? If you want AD, your best shot at it would be via AFROTC. But there's a catch, in order to be eligible for ADAF, you need to be selected to go to SFT. If you are not selected to go to SFT you lose your scholarship -- AND your only shot at commissioning. From what I heard it will be very unlikely to get selected to go to grueling, 12-week OTS when you can't even get through one, two years of ROTC. That's the way it is seen by the OTS selection board. So, that's one thing you must keep in mind. Here's a question for the cadre you can ask about this though; ask if the cadre holds there own sort of "mini-board" for selection. For example, I believe from one of Pima's posts that 90% of cadets that (for a lack of better words) apply for SFT, get selected. However .... that does not mean that the cadre will endorse every single cadet. Which, if you think about it makes sense, how 90% are selected to go to SFT. So that is one question you can ask.
LDAC on the other hand, all cadets to go. There's no selection board or anything like that.
On the flipside, if you are not seeking AD, and want Reserve/Guard go Army. The difference between AROTC and AFROTC is that for the Army, you are competing for AD commissioning based on your OML. One question you can ask the Army cadre is the percentage of cadets that get an AD commission. In the AF, once you are selected to go to SFT and successfully pass, you are automatically contracted and locked into 8 years (minimum) of AFAD (10 years for pilots).
Here is something else to consider (I am here myself). Where exactly do you see yourself after college? Do you see yourself in a particular branch over the other? If a pilot slot does not fan out, (not sure what MOS/SC is for biology) check to see how that MOS/SC differs, it may help you decide. If you are interested in making a career out of your service, it would be advisable to sit down and take a look at the pros/cons of each respective branch and find out what you do/don't like about each.
Since you said you want to be a pilot - what type of aircraft do you want to fly? Fixed wing = AF; rotary = Army. I will say though, if you want to fly in the AF, selection to UPT is difficult to attain. Direct quote from Pima:
Pima said:
Approximately 30% of UPT students do not wing.
For those that want fighters, it is @10% of the 70% left. Now add in AFROTC attrition rate, and you can see, very few 18 yos will get a fighter. Maybe out of your starting class...1 or 2.
Not trying to discourage you, just making you aware of the facts.
On the other hand, if you want rotary something to consider is - whether you want to know what you will be flying from the getgo or not. I believe from a recent post about NG aviation, when you go to flight school for the NG you will know what you will fly once you complete aviation school. On the other hand, ADA you wont know what you will fly until the end of aviation school. If you want to fly with someone like 160th SOAR (SF) you will have to go AD. Jcleppe will have more information about this than I will.
Also, if you can, try to talk with some Servicemembers from each branch. It will help you get a good perspective of what each branch is like. Ask them what they do/don't like about the respective branch they are in. If you don't know anyone off the top of your head, try your school faculty, there may be one or two there. For example, at my middle school, my former teacher is currently is a 1SG (prior mustang officer w/ cross-service experience) w/ the PNG. We had a nice conversation the other day about this topic (choosing between Army & AF).
To answer your other question, the questions you listed in your post are wonderful questions to ask.
Honestly, I can't really think of too much else to ask the cadre. Maybe someone else with a different perspective will give you better insight of questions to ask the cadre - but for me, this is how I see it (...for myself at least). Because if you are looking into career Military - I wouldn't focus too too much on the particular program, but rather the bigger picture, of which branch do you want to Serve with. It really comes down to what YOU want to do, not necessarily what the program has to offer.
Best wishes!
