Basically,

you would have to modify some of the subject names,
because the subjects in the code are mine, and you probably don't have the same ones ;)

after modifying, you start the code with /calc.gpa
you click the grade you have, and every field will be filled out.
when you fill all of em up, you click DO THE MATH button,
and it will calculate your grade point average :)
