Points-based grading
| Work | Earned | Possible |
|---|---|---|
| Homework | 45 | 50 |
| Exam | 80 | 100 |
| Total | 125 | 150 |
125 ÷ 150 × 100 = 83.33%
The exam has twice the influence because it offers twice as many points.
LESS BUSYWORK. MORE TEACHING.
Grading Calculator
Compare points and category weights, then choose the method in your syllabus.
A grading calculator helps you choose a method: total points divides all earned points by all possible points; weighted grading combines category percentages using syllabus weights. Choose the method your course uses, because the same scores can produce different averages. Calculate total points below; use the home gradebook for category weights.
Example: 45/50 and 80/100 give 125/150 = 83.33% by total points, or 84% when weighted 40% and 60%.

Which model does your syllabus use?
Look for how the course total is defined. Bigger point values alone do not mean category-weighted grading.
Total points
“This course has 500 possible points.” Each point counts equally. A 100-point exam has twice the influence of a 50-point assignment.
Use the total-points calculatorCategory weights
“Homework 40%, exams 60%.” The percentages set each category’s influence, even when its possible points differ.

| Work | Score | Weight | Contribution |

| Homework | 90% | 40% | 36 |
| Exam | 80% | 60% | 48 |
90 × 0.4 + 80 × 0.6 = 84%
The syllabus weights replace the point totals as the source of influence.

Grading Calculator: frequently asked questions
Why do points and weighted grading produce different results?
Total points gives larger possible-point totals more influence. Weighted grading uses the percentages specified by your syllabus, regardless of each category’s point total.
Which method should I select?
Choose Total points for a course described as a fixed number of available points. Choose Weighted grades when the syllabus assigns category percentages such as exams 60% and homework 40%.
Does a zero-point assignment count?
No. Possible points must be greater than zero. Remove an ungraded assignment instead of creating a zero-point row. For extra credit, use the extra-credit option with a positive possible-point total.
