How Final Grade Calculation Works
Your overall course grade is a weighted average of all your work. The final exam typically carries a fixed percentage (e.g., 30%) of your total grade.
The formula to find what you need on the final is:
needed = (target − current × (1 − weight)) ÷ weight
For example, if you have an 78% and your final is worth 30%, you'd need a 90% on the final to finish with an 81.6% overall (B-). This calculator handles the math instantly so you can focus on studying.
