What is a Test Score Calculator?
A test score calculator converts raw point totals into percentage scores and letter grades. This is essential for understanding your performance on exams, quizzes, homework assignments, and other graded work. Teachers often provide raw scores, but knowing the percentage helps you understand how well you actually performed and where you stand relative to grading thresholds.
This tool is useful for students checking their grades, teachers calculating scores for their classes, and parents helping track their children's academic progress.
Test Score Formula
The percentage is calculated using this straightforward formula:
Percentage = (Points Earned / Total Points) x 100
For example, if you scored 42 points on a 50-point test: (42 / 50) x 100 = 84%, which is a B grade.
Standard Grading Scale
The following grading scale is commonly used in American schools and universities. Note that some institutions use slightly different cutoffs or include plus/minus grades:
Understanding Grade Thresholds
The "Points Needed for Each Grade" section shows exactly how many points you need to achieve each letter grade on the test. This helps you understand:
- How close you were to the next grade level
- Whether you achieved your target grade
- How many points you can afford to miss while still earning your desired grade
Understanding Your Score
- Percentage: Shows what fraction of the material you demonstrated mastery of
- Points Missed: Indicates how many points you lost and where you have room to improve
- Score Ratio: Displays your raw score in fraction form for easy reference
- Missed Percentage: Shows what portion of available points you did not earn
Tips for Improving Test Scores
