How EZ Grader Makes Grading Simple?

Grading tests, quizzes, and assignments manually can be time-consuming. EZ Grader simplifies this process by turning complex calculations into a few quick inputs. Here’s how it makes grading simple:

Instant Calculation

Instead of calculating percentages and converting them to letter grades manually, you just enter the total number of questions and the number of incorrect answers. Our tool instantly generates:

  • The number of correct answers
  • The percentage score
  • The letter grade

Eliminates Manual Math

For example, if a quiz has 40 questions and a student gets 7 wrong, calculating the percentage manually would require:

Percentage = 40 − 740 × 100 = 82.5%

Our ez grade calculator does this automatically and provides you with the correct grade answers.

Total Questions Wrong Answers Correct Answers Percentage Letter Grade
50 8 42 84% B
30 5 25 83% B
40 2 38 95% A

  • Get correct answers, percentage, and letter grade instantly.
  • Works for any test size, from small quizzes to full exams.
  • Eliminates errors and saves time.
