text: Making students not participate in sports or another activities unless they have a grade B average isn't fair for many reasons. First of all, many students have a grade C average. Which is saying that it's difficult to keep a grade B average. Many students wouldn't be participating in sports or other activities. For those of the students that are maintaining a grade B average or higher that would want to be in sports probably wouldn't be able to because there aren't many, so there wouldn't be enough to have a team. The school would be missing out on so much if you did this.
