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.
