Calculate your overall class grade using categories with weights (homework 20%, tests 40%, final 40%) or by total points earned vs. possible. Both methods provide instant percentage and letter grade results.
Enter each grade category (homework, quizzes, tests, final) with its weight and your score.

How to Use the Class Grade Calculator
This calculator gives you two modes for computing your overall class grade. Use By Category when your syllabus assigns percentage weights to each type of work. Use By Points when your professor just assigns point values to each assignment and grades by dividing total points earned by total points possible.
By Category: Enter each graded category (Homework, Quizzes, Tests, Final), its weight %, and your score %. Weights should total 100%.
By Points: Enter each individual assignment with the points you earned and the total points possible. No weights needed.

By Category Formula
Class Grade = ฮฃ(Category Score ร Weight) รท ฮฃ(Weights)
Use By Category when: Your syllabus says "Homework counts 20%, Tests count 40%, Final counts 40%." You enter averages or overall scores for each category.
Use By Points when: Your professor says "Each assignment has a point value and your grade is total points earned divided by total points possible." You enter every individual assignment.
When in doubt, check your course syllabus or learning management system (Canvas, Blackboard) โ most systems display which method is used.

Frequently Asked Questions
By Category uses weighted averages where each type of work (homework, tests, final) is assigned a percentage importance. By Points totals all points earned and divides by all points possible โ each assignment's influence is proportional to its point value, not a predefined weight. Most professors use one or the other, and you can find out which from your syllabus.
Yes โ that's exactly what the By Points method is designed for. Assignments worth more points (e.g., a final exam worth 200 points) automatically have more influence on your grade than small assignments (e.g., a quiz worth 20 points), because the formula simply adds up all points earned and divides by all points possible.
For the By Points method, you can group similar assignments. For example, instead of entering 20 individual homework assignments, you can enter one row: "Homework" with the total points earned across all homework assignments and the total possible. This gives the same result while being much faster to enter. Alternatively, use By Category to enter your homework average as a percentage.
If your professor drops the lowest score (common for quizzes), simply don't include that lowest score in your entries. Add all other quiz scores, excluding your lowest. The calculator will compute your grade based on the scores you enter. If you're unsure which score will be dropped, run the calculation both ways to see the difference.
Canvas and Blackboard use either weighted categories or total points, matching our two modes. Results should be very close if you enter the same data. Minor differences may occur if the LMS handles dropped scores, extra credit, or grade rounding differently. Our calculator is a planning tool โ always check your LMS for the official running grade.
