text: Students should get as much physical activity as they want, but if they have to have a B average, then this will make them get worse at what they may do best. These people should be getting enough freedom to do an activity for at least a C average. They will lack in physical skills and it may even mess up peoples dreams. If you know most of your students maintain at a C average, then leave them like that. Of course, changing the policy might make them work harder, but its just not fair.
