What Your Result Means

How This Calculator Works

You enter each grading category (homework, quizzes, exams, etc.) with its syllabus weight, your score, and the total possible points. The tool converts each score to a percentage, multiplies by the weight, sums the weighted scores, and divides by total weight to get your overall grade. It then maps that to a standard letter grade.

Quick Questions

What if my weights don't add up to 100%?

The calculator still works — it divides by the total weight you entered, effectively normalizing. But for the most accurate picture of your grade, enter all categories so weights total 100%.

How can I figure out what I need on the final?

Enter all your current categories with their scores, then adjust the final exam score until the overall grade reaches your target. This lets you see exactly what final exam score you need.

Does this work with points-based grading?

Yes. If your class uses total points instead of weighted categories, enter one category with a weight of 100%, your total points earned as the score, and total points possible as "out of."

My instructor uses a different letter grade scale. Can I adjust it?

The calculator uses the standard 10-point scale (90/80/70/60). If your instructor uses a different scale, use the percentage result and refer to your syllabus for the corresponding letter grade.
