How it is calculated
Each letter grade is worth a number of grade points: A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0, with plus and minus grades in between (A- = 3.7, B+ = 3.3 and so on: the College Board table lists the whole letters only, the plus and minus values are the usual convention). Your GPA is the average of those points, weighted by the credits (or hours) of each course: Σ(points × credits) ÷ Σ(credits).
A weighted GPA gives harder classes extra points. Many US high schools add 0.5 for honors and 1.0 for AP or IB classes, so an A in an AP class counts as 5.0. Schools do not all use the same bonuses, and some colleges recalculate GPAs their own way, so treat the weighted figure as an estimate and check your school’s policy.

Questions people ask
- Is A+ worth 4.3?
On the standard 4.0 scale used here, an A+ counts as 4.0. A few schools give 4.3; if yours does, your transcript will say so.
- How do I convert marks out of 20 to a GPA?
There is no single official conversion. Universities and credential evaluators each use their own table, so ask the university you apply to which one it uses.
