What do you guys think is the best way to calculate weighted GPA?
Let your school do it.
I don’t think my school gives it to me, same with class rank. Even if they do it won’t be for another year, I would like to know now if possible.
Look in your student hand book. Every school uses their own weighting system. That’s why most colleges don’t use weighted GPA (it varies too much among school systems).
If you are applying to a college, and the college has a weighted GPA method, use that method (note that the methods may be different at different colleges). For example, students applying to California public schools would use the method described at http://www.csumentor.edu/planning/high_school/gpa_calculator.asp .
