How to use it
Add your completed assignments and the hypothetical scores you might earn on remaining work. The calculator shows your resulting weighted average.
Formula
Projected grade = Σ(weight × grade) ÷ Σ(weight)Examples
Example: Homework 85% (30), and 'what if' the final is 75% vs 95% (70)? At 75%: (30×85 + 70×75) ÷ 100 = 78%; at 95%: (30×85 + 70×95) ÷ 100 = 92%.
Example: You have 88% over 60% of the course. What if you score 90% on the remaining 40%? Projected = 88 × 0.6 + 90 × 0.4 = 88.8%.
Frequently asked questions
What is a what-if grade calculator?
It lets you test hypothetical scores to see how they'd change your final grade before committing.
How is it different from the final grade calculator?
The final grade calculator solves for the score you *need*; the what-if calculator shows the outcome for a score you *choose*.
Can I test multiple scenarios?
Yes — change the hypothetical scores and re-calculate to compare outcomes.
