text: My first reason is what I believe that will come into effect immediately. If students really want to participate in extra curricular activities, then the will try even harder then they were before. There are students that would go the extra mile to be on a sports team or join other activities. These students will seek additional help if they do not believe they can maintain B averages. On the downside, there will be a few students who will not want to work to get the B average and they will not participate in sports or other activities. This could cause the sports teams to become less talented then they were before because some of the talent might not care enough to try and get the B average. But, if you would like your students to try and work more efficently and coopretively, then this policy could be the right the thing to enforce in the school.
