How to Use

Points mode uses points earned ÷ points possible × 100.

Weighted mode solves the required test percentage from your current grade, weights, and target.

FAQs

How do I convert points to a percentage?

Divide points earned by points possible and multiply by 100. The calculator also shows the corresponding letter grade.

What does an answer above 100% mean?

It means the requested course target is not achievable from the remaining test under the entered weights.

Use Cases

Determine your test performance

Quickly convert points earned into a percentage and letter grade to see how well you did on a test.

Example: If you earned 18 out of 20 points, your percentage is 90% (A-).

Plan for a target course grade

Calculate the minimum score needed on an upcoming test to achieve a desired final grade in the course.

Example: With a current grade of 85%, a test weight of 30%, and a target of 90%, you need 101.67% on the test.

Frequently Asked Questions

How do I calculate my test percentage and letter grade?
Enter the points you earned and the total points possible. The calculator divides earned by possible and converts the result to a percentage and a letter grade based on the standard grading scale.
How can I find the score I need on a test to reach a target course grade?
Provide your current grade, the weight of your current work, the test weight, and your target course grade. The calculator computes the required test score as a percentage to achieve that target.
What if my current work weight and test weight don't add up to 100%?
The calculator uses the weights you enter to compute the required test score. Ensure the sum of current work weight and test weight equals 100% for an accurate result.

Tips & Common Mistakes

Tips

  • Double-check that the points possible is greater than zero to avoid division errors.
  • When calculating the required test score, ensure the sum of current work weight and test weight equals 100%.
  • Use the letter grade as a quick reference, but always check your school's specific grading scale.
  • If your target course grade is higher than 100%, the calculator will show that it's impossible to reach with the given weights.

Common Mistakes to Avoid

  • Entering points earned as a percentage instead of actual points (e.g., 90 instead of 18 out of 20).
  • Forgetting to convert weights to percentages (e.g., using 30 instead of 0.30).
  • Assuming the letter grade scale is universal; it may vary by institution.
