I had multiple soccer scholarships in high school. I took one at a D-1 junior college. It was pretty serious and we traveled all over. Even played the defending national champs. In my experience, I don't think it could have been done...
We practiced from 630 to 730 am. Then a 3-5 pm practice, then 9-10 practice everynight. During school. Long story short, I left after the season to play at a school closer to home with more career choices but went to college at home for a semester and liked it so much I stayed. I really don't see how it could be done. It all depends on your school and practice/game schedule, but you will be expected to be at EVERY practice, and work on your regular classes while flight training. In my experiences, that would have been a recipe for disaster. It can be done, but kiss your social life goodbye. Life's too short to be that serious.
My advice, give up the soccer and play intramural or club soccer if you'll miss it too much. I really don't mean to sound rude, but you're going to have to give it up someday(otherwise you wouldn't need to go through flight training

, really) You could also try it for a semester, but I can almost guarantee your schedule will be miserable. Soccer chicks are hot, playing college sports is a blast, but you might want to start thinking about longevity. On the other hand, if you're entirely sold on flying, play soccer and take general eds for a semester and get a better feel for what you want to do. Personally I just don't think doing both would be much fun.
Good luck with whatever you choose and more importantly, have fun and lay it all out!
