What is a Test Grade Calculator?
A test grade calculator is a digital tool that helps students and teachers quickly determine academic scores. By inputting earned points and total possible points, it automatically calculates the percentage score and corresponding letter grade. This tool eliminates manual calculations, reduces errors, and provides instant results. It's particularly useful for educators grading multiple papers, students checking their performance, or anyone needing to convert numerical scores to percentage grades. The calculator typically follows standard grading scales (A-F) and can accommodate different grading systems. It simplifies score interpretation and helps in academic assessment processes.

Grade Calculation Formula
Percentage Formula: (Earned Points ÷ Total Points) × 100 = Percentage Score
Letter Grade Scale:
A: 90-100%
B: 80-89%
C: 70-79%
D: 60-69%
F: Below 60%
