if you have half a brain its really not all that hard. especially if you are in public school.
I was at a public school in all honors classes and training for varsity soccer. I know from experience its not easy. You get out from school around 3pm, sprints/runs took 1-2 hours. Drills took an hour. Scrimmage for another hour, then more drills and then finally work with the trainers. By the time you get home its 8pm; where's the time to do work to maintain a grade point average. You say its easy, to me it was pretty hard.
