How to Calculate Final Grade
To determine what you need on your final exam, we use the weighted average formula. Here is the math we use:
(Target - Current * (1 - Weight)) / Weight
Example
You have an 85% average. You want a 90% (A-). The final is worth 20%.
- The 85% accounts for 80% of your grade.
- The final accounts for the remaining 20%.
- You would need a 110% on the final to reach a 90% average. (Better ask for extra credit!)
