Calculate Weighted Grade
Enter your assignments with their weights and scores. Weights should be percentages that total 100%.
Understanding Weighted Grades
A weighted grade system gives different importance to different assignments. For example, a final exam worth 40% of your grade matters more than homework worth 10%.
The Formula: Weighted Grade = ฮฃ(Score ร Weight) รท Total Weight
Example: If homework (20%) = 90%, midterm (30%) = 85%, final (50%) = 88%:
Weighted = (90ร20 + 85ร30 + 88ร50) รท 100 = 1800 + 2550 + 4400 รท 100 = 87.5%
Why Weighting Matters: Without weighting, a 100% on homework would boost your grade unfairly. Weighting ensures your grade reflects your performance on what matters most.
Common Weight Distributions: Typically exams = 40-50%, homework = 20-30%, projects = 15-20%, participation = 5-10%. Check your syllabus for exact weights.
