How Credit-Weighted GPA is Calculated
Unlike a simple arithmetic average that treats every class equally, college and high school GPAs are credit-weighted. Courses that meet more frequently or include labs carry higher credit values and exert a proportionately greater impact on your cumulative academic record.
