Overview & Core Concept
Cumulative points systems avoid category weights by making every point equal.
Mathematical Formula
\text{Grade} = \frac{\sum \text{Earned}}{\sum \text{Possible}} \times 100Step-by-Step Instructions
Add all points earned
Sum points across homework, labs, and exams.
Add all points possible
Sum total points available.
Divide
Divide earned by possible and multiply by 100.
Realistic Worked Example
Points System Walkthrough
Homework (90/100), Midterm (180/200), Quiz (45/50).
- Earned = 315
- Possible = 350
- 315 / 350 = 90.0%
Final grade is 90.0% (A-)
Key Takeaways
- Every point is identical in mathematical weight.
