First, see if you can even finish getting through college, whether it is a Service Academy or civilian college.
Then, IF you get picked up for IFS, and *IF* you can get through IFS, we'll talk about the full year of 15 hour days at UPT.
My son was picked up to be a C5 "driver" and he missed only 3 of 845 questions during UPT. The C5 was his first choice, not the fighters or bombers, and there are more factors that weigh into your decision than "I want to be that guy." I have even heard cadets say things like: "If I don't get a fighter I don't want to be in the Air Force." OK, then... well, I will say that THAT kid didn't make it through USAFA.
PIMA is right. You are on step 6. While it is good to have goals and especially good to work toward them, don't worry about step 1000 until you get to about 300.
