text: Most students have C averages and are trying as hard as they can, but if they were looking forward to playing a school sport and they had to have a B average then that student will probably not try harder either because they know that it would too much for them to handle or some people just have low self esteem. So if the grade average was a C' s then their self esteem will be raised because not only are they truly putting in as much effort as they can but they get to play the school sport they wanted to play and feel good about them selves.
