Out of 15 Grading Chart
Every possible score on a 15-point test — from 15/15 (100% A) down to 0/15 (0% F) — with its percentage, letter grade, and GPA equivalent on the standard 4.0 scale.
When is a 15-Point Test Used?
Fifteen-question quizzes appear often in middle school and high school classrooms as unit-review checks. Each question is worth roughly 6.7 percentage points, so two wrong answers already drops a score to an 86.7% — a B.
The letter grades below use the standard US 10-point scale: A (90–100%), B (80–89%), C (70–79%), D (60–69%), F (below 60%). GPA values follow the 4.0 unweighted scale (A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0).
