FAQ
How is a weighted grade calculated? Each score is multiplied by its weight, the results are added together, and the total is divided by the sum of the weights. Weights are normalized automatically if they don’t total 100%.
What score do I need on the final? Enter your current grade (without the final), the grade you want, and the final exam’s weight — the calculator solves for the exact percentage you need.
What if the needed score is above 100%? The calculator tells you honestly: your desired grade is not reachable with this final weight, so you can adjust your target.
