I would just like to point out Asvab scores are not everything...
You are in for a lot of studying, and a lot of hardwork. this is something I gaurentee you have never experienced before. To ease your mind, I want to tell you that the material itself is not that hard. Its actually barely considered advanced. The real problem with this school is its 1) stressful 2) EXTREMELY fast paced, and 3) people who fail 80% of the time dont like to work for it.
You seem to be the type that is scared of failing and will be willing to work. Not a "hot shot, im smarter then everyone" type that seems to pop up... (im not one of those... right? haha. search my posts. I was COCKY
). You should do fine with adequate work effort involved. Just keep in mind you are still in the military and htat means a lot of things, not just academic. Keep your nose clean, chin up, and STUDY HARD!
Dont ever give up, everyones willing to help you out if you are willing to work for it.
