FAQ
Can I enter decimals?
Yes. Include decimal grades such as 89.5 for finer resolution.
How do I handle missing assignments?
Enter a zero or the minimum allowed grade to see the impact of missing work on the overall average.
Is this a weighted average?
No. All three inputs contribute equally. For weighted grading, multiply each score by its weight before summing.
Can I use more than three scores?
This version accepts three values. For more scores, average groups of three or use a spreadsheet for flexibility.
Additional Information
- This tool computes the arithmetic mean, treating each score with equal weight.
- Use consistent grading scales—percentages, points, or letter-grade equivalents—to keep the result meaningful.
- If your course uses weights, convert the scores to weighted points before averaging or use a weighted-average calculator.
- Track averages over time to spot trends and identify subjects needing extra study.
