Frequently Asked Questions
What happens if my category weights do not add up to 100%?↓
If final exams have not occurred yet (e.g. only 65% of the course has been completed), this calculator automatically normalizes your grade by dividing by the sum of completed weights, showing your true current standing.
Can this calculator handle extra credit categories?↓
Yes. You can enter an extra credit category with a score above 100%, or input category scores greater than 100% if bonus points were earned.
How does this tool differ from a simple average?↓
In an unweighted average, every assignment counts equally. In a weighted course, a 20-point quiz carries far less influence than an 80-point final exam because their respective syllabus weights dictate their impact.
What limitation applies if you want to know what score is required on the final exam?↓
If you want to calculate the exact target score you must achieve on the upcoming final exam to secure an overall course grade, use our Final Grade Calculator.
