Frequently Asked Questions
How is GPA calculated?
GPA = Total Grade Points ÷ Total Credits. Each course's grade points = Grade Value × Credits. Then divide the sum by total credits.
What is a good GPA?
3.0+ is generally considered good. 3.5+ is very good (Dean's List at many schools). 3.7+ is excellent. Requirements vary by program and school.
Do all schools use the same GPA scale?
Most US schools use the 4.0 scale, but some differences exist. Some give A+ a 4.3, others cap at 4.0. Some don't use +/- grades. Check your school's policy.
