How to Calculate Your Grade with Weighted Scores

Most courses don't give equal weight to everything. Here's how to calculate your final grade when different assessments have different percentages.

The Weighted Average Method

1. List all assessments (quizzes, assignments, midterm, final, etc.)
2. Multiply each score by its weight (weight ÷ 100)
3. Sum all these values to get your final grade

Example

• Assignments (30%): Score 85/100 → 85 × 0.30 = 25.5
• Midterm (30%): Score 78/100 → 78 × 0.30 = 23.4
• Final (40%): Score 92/100 → 92 × 0.40 = 36.8
• Final Grade: 25.5 + 23.4 + 36.8 = 85.7%
