Test Grade Calculator

Convert correct answers to percentage and letter grade

Test Grade Calculator

A test grade calculator converts a raw score (number of correct answers out of total) into a percentage, and optionally maps that to a letter grade. Different institutions use different grading scales — the US A-F scale, UK degree classifications, or percentage thresholds.

  1. 1Percentage = (Points earned / Total possible points) × 100
  2. 2Weighted score: each section × its weight percentage, then sum
42 correct out of 55=76.4%42 ÷ 55 × 100 = 76.36%
Sections: 80% (40% weight) + 70% (60% weight)=Overall: 74%0.8×40 + 0.7×60 = 32 + 42 = 74%
