I don't know if this will be of use to anyone, but if so, here it is. Despite its ability to harm me when the grades come in lower than my worst-case scenarios, I use this spreadsheet to track my GPA and to see where it's heading based on what's coming up. Just change the letter grade next to the appropriate class and see the result.

Right now, it's got the classes I've taken or am taking, a fictitious grade (well, they're not all fictitious) and the USF grade-point scale.

If you want to modify classes, be sure to modify the hours accordingly. If you want to add classes, be sure to copy the formulas down.

There's nothing too fancy here, but maybe someone may find it useful.
