Frequently asked
What's the difference between weighted and unweighted GPA?
Unweighted GPA caps every class at 4.0. Weighted GPA gives extra points (often a full grade) for honors, AP, or IB classes, so an A in AP Physics can count as 5.0 instead of 4.0.
What's the 4.3 scale?
Some schools award 4.3 for an A+. It's still 'unweighted' but rewards perfect scores. Check your school's policy before using it.
How are credit hours weighted?
Each course contributes grade-points × credits. Total grade-points are divided by total credits to get your GPA.
