Frequently Asked Questions
No, there is no universal formula. Because grading policies vary drastically between high schools, a 90% at one school might be an 'A' (4.0), while at another it might be an 'A-' (3.7).
Colleges often have their own specific conversion tables. Many college admissions offices will take your 100-point transcript and completely recalculate your GPA on their own standard 4.0 unweighted scale so they can fairly compare you to other applicants.
Generally, on a standard letter grade mapping, a 90% to 100% falls into the 'A' range, which translates to a 4.0. However, if your school uses plus/minus grading, a 90% might be an A- which translates to a 3.7.
This depends on your high school. Some schools add points to your 100-point average for difficult classes (e.g., scoring a 95 in an AP class is recorded as a 105). You should ask your guidance counselor if your reported average is weighted or unweighted.
In the United States, the average unweighted high school GPA is typically around a 3.0 (a solid 'B' average), though these figures vary significantly depending on the specific region and the rigor of the school.
