Frequently Asked Questions
How is a weighted grade different from a regular average?
A weighted average accounts for the importance (weight) of each assignment. A final exam worth 50% affects your grade more than homework worth 10%.
What if I need more than 100% on my final exam?
If the calculator shows you need over 100%, it means your current grade is too low to reach your goal with the remaining weight. Consider extra credit or adjusting your target.
What grading scale does this use?
We use the standard US letter grade scale: A+ (97-100), A (93-96), A- (90-92), B+ (87-89), B (83-86), B- (80-82), C+ (77-79), C (73-76), C- (70-72), D+ (67-69), D (63-66), D- (60-62), F (0-59).
