## How to Calculate Participation Score

Participation scoring typically combines attendance, frequency of contributions, and quality.

### Formula

**Score = Attendance(40%) + Contribution Frequency(30%) + Quality(30%)**

- Attendance: Percentage of classes attended
- Contributions: Capped at 3 per class for full marks
- Quality: Scored 1-10 by instructor

计算示例

26 of 30 classes attended, 2 contributions per class, quality score 7/10.

  1. Attendance = (26/30) x 40% = 34.7
  2. Contributions = min(2/3, 1) x 30% = 20.0
  3. Quality = (7/10) x 30% = 21.0
  4. Total participation = 34.7 + 20.0 + 21.0 = 75.7%
