Chill,
They have one sememster to prove themselves then released from daily study hall. If not, it continues until they maintain the GPA that is required of them.
Even though my son is a good student, I feel that study hall will help him to learn how to manage his life in a new situation. Here you have kids living on their own for the first time, hectic schedule and tempted by the college social life, they really need to learn that disipline from the beginning. I also like that the coaches get weekly reports from the kids themselves.
Many schools have a once a week mandatory class where they learn about time management, the responsibility of being a student athelete, social skills, etc.
