Teachers have used slide-style “EZ graders” for decades: fix the number of questions, then read off the percentage for each possible number wrong. The math is score = (total − wrong) ÷ total × 100. This page generates that chart for any test size — enter the question count once and grade the whole stack from the highlighted table, including decimal wrong-counts for partial credit.

A single test score rarely stands alone — it usually enters a weighted category. If quizzes are 20% of your course and this quiz is one of five, it moves your course grade by at most 4 percentage points. To see the effect on your overall standing, put the category average into our Grade Calculator, and to find what you need on the final, use the Final Grade Calculator.
Calculate your weighted course grade from homework, quizzes, and exams — with letter-grade conversion and category weights.
Find the score you need on your final exam to reach any target grade, from your current grade and the final's weight.
Calculate college Grade Point Average with support for multiple courses, different grading systems, and credit hours.
