I'm a MID. I've hosted candidates and we definitely submit evaluations on everyone. These evaluations are rather in depth and are the first time the academy is able to gauge your whole person qualification. Try to actively participate in your host's daily lives and show interest in the academy...
i was in the same boat.
hey man,
im 4/C Grewal. Ill try to make this short. I had the exact same profile as you i'd say. my grades were decent in high school. i was on the USS Harry S Truman. I was an EM3 and thought i didn't stand a chance at all. my ACT scores were exactly like yours...
