I played collegiate soccer with my team over 2000 miles away from home. I think a lot of it will depend on what your major is. My first semester was crazy. I didn't have much time for anything but soccer, but I managed to keep up with my studies.
Second semester was a breeze since the training in spring was much reduced. However, sophomore year was even tougher...much tougher...I had just as much soccer and twice as much homework. I took 17 credit hours and I ended up failing one class...and I graduated first in my class in high school. Of course I'm majoring in Aerospace engineering so I'm taking some serious courses.
The next semester was not quite as hard although I had almost no free time. That was my last semester of soccer because of an ankle injury. I must say that now I'm glad I'm not playing soccer now that I'm a Junior. My grades would have been terrible and I barely had time to eat and sleep, let alone play soccer.
I admit, some people can do it, but from what I've seen on my team, it's caused poor grades and it's caused lots of people to have to graduate in 4 1/2 years instead of 4. Good luck with whatever you decide
(PS At least you get one day a week off...we went for over 1 1/2 months without a day off)
