Out of 30 Grading Chart
Every possible score on a 30-point test — from 30/30 (100% A) down to 0/30 (0% F) — with its percentage, letter grade, and GPA equivalent on the standard 4.0 scale.
When is a 30-Point Test Used?
Thirty-question tests balance enough questions for reliable coverage while staying manageable to mark. They appear in standardised practice tests, textbook chapter reviews, and many online assessments.
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).
