Military or civilian pilot?

I can address part of the AF side.  To be a USAF pilot, you must be an officer.  This means you need at least a 4yr degree and you must go through a commissioning program.  There are three main commissioning sources, the Air Force Academy (where I am), Air Force ROTC, and OTS.  OTS is a 3 month (I think) training program for ...

You do not need 20/20 to be a pilot.  You need within a certain limit, 20/70 last I recall, or a waiver, or eye surgery...for the USAF anyway.

You are missing sports.  That is a moderately big problem.  Not having calc will hurt, but it won't stop you.  I don't know if the Academy will consider being a life guard to be leadership (you are a bit slim on that area too).  The language thing is probably not important.  You cannot become an Eagle in two years, ...

My advice is do well in school, particpate in extracurriculars (leadership possitons if possible), and sports.  When you graduate HS, apply to the Air Force Academy and Air Force ROTC.  Do decently in college and get a slot for UPT (pilot training) when you graduate.

What matters for college is getting your credits/validations to be approved by your end college and keeping a high GPA.  GPA is the biggest factor in AFROTC ranking (which determines who gets to pick their job first).  Since both the degrees you mentioned are engineering degrees, I doubt it would make much of a difference which one you ...

I will not stop you from getting an OTS slot, but your odds are not as good as a person with a techie degree.  Also realize that OTS does not have a massive number of pilot slots.  I would do a lot of online research into it and try to find people who know/have done it.

ROTC ranks their cadets on GPA, fitness scores, and the detachment commander's evaluation (if I remember correctly).

Having a 3.3 in an engineering major at a good school shouldn't hurt too much.  I don't know exactly how competitive pilot slots are out of ROTC units now, but you never know until you try.

If you passed the subsequent tests, you should be fine.
