stick with an fbo/smaller flight school while going to college. Dont waste your money for no reason. I went to a regular university, didn't do anything related to aviation at college (agriculture economics degree), spent about 20,000 getting all ratings through mei-cfii while attending, taught at the small fbo and flew part 91 C310 and Piper malibu for a medical group in town on the side. When I graduated from college (22 yrs old) I had over 2000 hours total and 500 hours multi and was hired at my number one choice regional two months before I graduated. You don't have to attend any kind of "professional" school to get your ratings, its just something those places tell you but in reality its not necessary.
