College Admissions

Can you calculate it yourself by adding up grade points (A=4, B=3, C=2, D=1, F=0) for each semester of academic courses (excluding stuff like health and PE) and dividing by the number of grades?

Weighted GPA is meaningless outside of your high school, since others do not know the weighting method. Some may assume that your unweighted is a full point lower (e.g. 2.43 instead of 3.43), since some high schools have very heavy weighting.
