How it works
Assign base grade points (A=4.0 scale), add weight for course level, multiply by credits, divide total quality points by total credits.
Formula
Weighted points = (base grade points + level weight) × credits
Weighted GPA = sum(weighted points) ÷ sum(credits)
Worked example
An A in AP (4.0+1.0)*1 + B+ in Honors (3.3+0.5)*1 + B in Regular (3.0)*1 over 3 credits = (5.0+3.8+3.0)/3 = 3.93 weighted GPA.
Assumptions
Uses a common 4.0 scale with +0.5/+1.0 weights. Your school may cap weights or use a different scale (5.0 max).
Reading the result
Weighted GPA can go above 4.0 on some scales; check your school's reporting method.
