Types of Grading Systems

Percentage-Based Grading

Each assignment contributes equally.
Example: 5 quizzes worth 20% each → Total 100%.

Weighted Grading

Different categories (exams, homework, participation) have different weights.
Example:
- Exams: 50%
- Homework: 30%
- Participation: 20%

Points-Based Grading

Each assignment has a fixed point value.
Example:
- Midterm: 100 pts
- Final Exam: 200 pts
- Total course points: 500

How to Calculate Your Grade Manually

1. For Percentage – Based Grades

Formula:

Final Grade (%) = (Total Points Earned/Total Possible Points) × 100

Example:

Quiz 1: 85/100
Quiz 2: 90/100
Quiz 3: 78/100
Total earned = 85 + 90 + 78 = 253
Total possible = 100 + 100 + 100 = 300
Final grade = (253 / 300 ) × 100 = 84.33%

2. For Weighted Grades

Formula:

Final Grade = ∑(Category Grade×Weight)

Example:

Category	Grade (%)	Weight (%)	Contribution
Exams	85	50	85 × 0.5 = 42.5
Homework	90	30	90 × 0.3 = 27
Participation	75	20	75 × 0.2 = 15
Total		100	84.5%

3. For Points – Based Grades

Formula:

Final Grade (%) = (Points Earned / Total Course Points) × 100

Example:

Homework: 150/200
Midterm: 85/100
Final Exam: 180/200
Total earned = 150 + 85 + 180 = 415
Total possible = 200 + 100 + 200 = 500
Final grade = (415 / 500) × 100 = 83%
