I wanted to get a degree in something other than aviation but in the end Southern Illinois University had a good satellite program that I attended every other weekend in SoCal. I got my degree in Aviation Management. Yes the G550 is a great airplane to fly, you will get there. You should look into flight safety or simuflite with regards to their right seat program where you get paid to fly in the sim when a client needs a pairing. You could network the corporate world easily, get a biz jet type, get paid and finish school.
