This page is intended to help teachers curve tests. It does all the
math for you so you can concentrate on doing the actual grading. It
can also be used if you are not curving, by setting one field to "0"
Normally, I am not a fan of "grading on the curve" but we all know
there are times when it is called for. This page can also be used as
a grade chart if you are not curving, and can be printed out.
