How Letter Grades Become a GPA
Your GPA scale connects three things: a percentage grade from an assignment or class, a letter grade your teacher records, and a GPA point value used to calculate your overall average.
Step 1: Your Percentage Grade
| Assignment | Points Earned | Points Available |
|---|---|---|
| Homework Set 1 | 18 | 20 |
| Midterm Exam | 85 | 100 |
| Essay | 28 | 30 |
| Final Exam | 88 | 100 |
| Total | 219 | 250 |
Step 2: Convert to a Letter Grade
An 87.6% falls in the 87-89 range, which converts to a B+.
Step 3: Convert to GPA Points
A B+ is worth 3.3 points on the 4.0 scale.
Weighted Scales for AP & Honors Classes
AP, IB, and Honors classes are typically graded on a weighted 5.0 scale instead of the standard 4.0. See our full guide on AP/Honors weighting, or try the weighted grade calculator.

Is the GPA scale the same at every school?

What's the difference between weighted and unweighted GPA scales?
