What is the GPA Calculator?
GPA is a credit-weighted average: each course’s grade points (e.g. B+ = 3.3) are multiplied by its credits, added up, and divided by the total credits. A 4-credit course therefore counts twice as much as a 2-credit one.
Scales differ between schools — some give A+ = 4.3, others don’t use plus/minus at all. Check your school’s scale and pick the matching letter grades.
