Fórmula
In a points-based course, each assignment counts in proportion to its points possible.
Grade % = Σ points earned / Σ points possible × 100
Example
- 18/20, 42/50, 88/100 and 9/10.
- Earned 157 of 180 points.
- 157 / 180 = 87.22%, a B+ on the common US scale.
Preguntas frecuentes
Why is this different from averaging my percentages?
Averaging percentages gives every assignment equal weight. In a points system, a 100-point exam counts five times as much as a 20-point quiz.
What letter-grade scale is used?
The common US scale: A 93+, A− 90–92, B+ 87–89, B 83–86 and so on, with F below 60. Your instructor's scale may differ.
How can I find what I need on the final exam?
