How Weighted Averages Work

A weighted average multiplies each score by its weight, sums the results, and divides by total weight. For example, if homework (20% weight) averages 90% and exams (80% weight) average 75%, your weighted grade is (90 x 20 + 75 x 80) / 100 = 78%.

Examples

Weighted Average Calculation

A student has homework (20% weight) averaging 90%, quizzes (20% weight) averaging 85%, and exams (60% weight) averaging 78%.

Weighted grade = (90 x 0.20) + (85 x 0.20) + (78 x 0.60) = 18 + 17 + 46.8 = 81.8%. The exam category has the most impact because it has the highest weight.

Key takeaway: Focus on improving categories with higher weights for the greatest impact on your overall grade.

Maximizing Your Weighted Grade

Tips for improving your weighted average:

Identify categories with the highest weights and prioritize them
A small improvement in a high-weight category matters more than a big improvement in a low-weight one
Do not neglect low-weight categories entirely - they still contribute
Check your syllabus for the exact category weights in your course
