Easy Grader
QuickGrade turns wrong answers into percentage scores in a single tap. It's the fast, mobile-friendly grade calculator built for real classrooms — no plastic wheel, no signup, no clutter.
Grade Calculator
Letter grades in the quick result use the flat 10-point scale (90–100 = A, 80–89 = B, and so on). Supports up to 500 questions.
How to Calculate a Test Grade
Use this formula to calculate a percentage score:
For example, if a student answers 22 out of 25 questions correctly: 22 ÷ 25 × 100 = 88%. The student's score is therefore 88%.
QuickGrade does this calculation automatically, but understanding the formula helps teachers and students check results manually.
