Grading Charts by Test Size
Pick a test size below to open a complete grading chart — every possible score listed with its percentage, letter grade (A–F), and GPA on the standard 4.0 scale. Perfect for teachers who need a quick-lookup reference while marking a class set.
How a Grading Chart Works
A grading chart converts raw scores into percentages using the formula:
Percentage = (Score ÷ Total) × 100
Letter grades follow the standard US 10-point scale: A (90–100%), B (80–89%), C (70–79%), D (60–69%), F (below 60%). GPA uses the unweighted 4.0 scale (A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0).
Select a denominator card to view the full chart for that test size, or use the Test Grade Calculator for an interactive version where you can enter any total.
