Tips & Tricks
- If your teacher uses a non-standard grading scale, use the percentage result and compare it against your specific class's scale rather than the default letter shown here.
- For a full class average across multiple assignments, use the semester grade calculator instead of calculating one test at a time.
- Double check you're using the right 'points possible' - extra credit questions can sometimes shift this number.
- Save your results each time to track your performance trend across the semester.
Frequently Asked Questions
What grading scale does this use?
The standard U.S. scale: 97-100 = A+, 93-96 = A, 90-92 = A-, and so on down to F below 65. See the full GPA scale chart.
Can I use this for a full class average, not just one test?
For multiple assignments, use the semester grade calculator instead.
What if my teacher uses a different grading scale?
Use the percentage result from this tool and compare it against your specific class's own scale.
Does this account for extra credit?
Yes, as long as you include any extra credit points earned in your 'points earned' total.
Can I calculate a negative or curved score?
For curved grades, use the grade curve calculator instead.
What if points possible is zero?
The calculator can't divide by zero - make sure you enter the actual total points the assignment was worth.
Is this the same as the EZ Grader?
Similar purpose, but the EZ Grader is built around question counts (right/wrong) instead of point totals - use whichever matches how your assignment is scored.
Can teachers use this for grading a whole stack of tests?
Yes, though the EZ Grader may be faster if you're working from a fixed question count.
Is decimal precision supported?
Yes, you can enter decimal point values if your assignment used partial-point scoring.
Is this tool free?
Yes, completely free with no sign-up required.
