You need 92.56% on the remaining 35% of your grade to finish at A- (90%+).
A weighted grade counts some work more than others. Enter each category's score and the weight your syllabus assigns it; this calculator multiplies each earned fraction by its weight, adds them, and divides by the total weight. A 95 on homework worth 20% and a 70 on an exam worth 80% yield a 75, not an 82.5.
The formula
Heavier categories move the average more. The exam at 80% weight dominates the homework at 20%, which is why a simple average overstates a grade with one big-weight component.
How to use it
- 1
List your grade categories
Add a row per category — homework, quizzes, midterm, final — with the score you earned out of its maximum.
- 2
Assign the syllabus weights
Enter each category's weight as the percentage of the course it counts for. The weights can total 100 or any consistent set of numbers.
- 3
See the true weighted grade
The result is the weight-adjusted percentage, which differs from a plain average whenever the categories carry unequal weight.
Frequently asked questions
- Why is my weighted grade lower than the simple average?
- Because a high score sits in a low-weight category. The average treats every score equally; weighting lets a heavy exam pull the overall grade toward its value.
- Can I mix percentages and point weights?
- Keep one system per calculation. Use all percentages (
20/30/50) or all point values, since the tool normalizes by whatever total you enter. - How do I handle a category with several grades?
- Average that category's scores first, enter the result as one row, then give the row the category's full weight.
