How to calculate a weighted grade from your syllabus

Short answer: multiply each category's average by its weight, add the results, and divide by the total weight that has been graded so far.

1. Find the weights

Your syllabus lists them, for example homework 15%, labs 15%, midterm 30%, final 40%.

2. Average each category

Homework 10/10, 9/10 and 10/10 averages 96.7%. Labs 47/50 and 45/50 average 92%. Midterm 86%.

3. Multiply and add

96.7 × 0.15 + 92 × 0.15 + 86 × 0.30 = 14.5 + 13.8 + 25.8 = 54.1.

4. Divide by the graded weight

Only 60% of the grade is in so far (15 + 15 + 30). 54.1 ÷ 0.60 = 90.2%. That is your current grade — and the final's 40% decides the rest.

How Gradora helps

Enter the same categories and weights once. Every new score updates the current grade, shows how much of the grade is in, and tells you what you need on the items that are left.

FAQ

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

Divide by the total of the weights you used. If your syllabus lists 90% plus a 10% participation grade, include participation too.

How do I handle extra credit?

Most classes add it on top of the weighted grade. Check your syllabus; in Gradora you can enter bonus points per class.

Is a weighted grade the same as an average of all scores?

No. A 100% on a 5% homework moves your grade far less than a 70% on a 40% final.
