How to Calculate Test Grades
This Test Grade Calculator instantly computes your exam score based on the number of correct answers or points earned. Whether you are a student checking a quiz result or a teacher grading finals, this tool provides the percentage, letter grade, and a visual performance breakdown.
Example: Answering 42 out of 50 questions correctly results in an 84% (B).
How to Calculate Test Grades
Calculating your grade after a test is straightforward, but it depends on whether your teacher grades by the number of questions or by total points. This tool handles both methods.
Method 1: Question-Based Grading
Use this when every question is worth the same amount.
Method 2: Points-Based Grading
Use this when questions have different weights (e.g., multiple choice is 1 point, essay is 10 points).
Detailed Example Calculation
| Scenario | Input | Math | Result |
|---|---|---|---|
| Quiz | 18/20 Correct | (18 ÷ 20) × 100 | 90% (A-) |
| Final Exam | 125/150 Points | (125 ÷ 150) × 100 | 83.3% (B) |
Understanding the Grading Scale
While schools vary, the standard US grading scale used by this calculator is:
- A (90% - 100%): Excellent performance.
- B (80% - 89%): Good performance, above average.
- C (70% - 79%): Average performance.
- D (60% - 69%): Below average, but passing.
- F (0% - 59%): Failing grade.
