text: I don't think that it is a good idea to change the grade average to a B. A C is a passing grade, and trying to keep up a grade B while playing sports could sometimes be really hard. Kids have a lot to do and maybe going through some rough times, and are already trying there best to keep up with a grade c. To get you thinking about why you should not change the grade average to B, i will give you some reasons of my own.
