text: I agree with you 50% because if a student has a low grade, and participates in school sports, their grades could drop even lower because they might not be able to finish their homework. The other 50% goes to: you should also let students know ahead of time when a sport is coming up, so they can get their grades up and be in the sport of their choice. I also think you should try that the parents should be able to say if their kids can be in sports if their grades are low; you probably wouldn't get as many complaints from parents and students that way.
