The Exam Exam Calculator compares performance across two exams and combines them using adjustable weights. The unusual title is preserved from the project list; functionally, the page is a two-exam comparison and weighted-average calculator.
Use it to measure improvement from one exam to the next, calculate a combined exam average, or determine the score needed on the second exam to reach a target weighted result. Scores are entered as percentages, while weights can be any positive relative values.
1. Enter both exam scores
Use percentage scores from 0 to 100.
2. Assign relative weights
Enter each exam’s contribution. Values of 40 and 60 are equivalent to 2 and 3.
3. Set a target
Choose the combined exam result you want.
4. Compare performance
Review the change from Exam 1 to Exam 2 and the simple average.
5. Check the required second score
The target calculation holds Exam 1 fixed and solves for Exam 2.
Weighted average = (Exam 1 score × Weight 1 + Exam 2 score × Weight 2) ÷ (Weight 1 + Weight 2)
Exam 2 score needed = [Target × (Weight 1 + Weight 2) − Exam 1 score × Weight 1] ÷ Weight 2
Scores and the target are percentages. Weights are relative and do not have to sum to 100.
The main result combines two exam percentages according to their entered importance.
This calculation does not include assignments, attendance, or other course components.
Given: Exam 1 is 76% with weight 40, Exam 2 is 84% with weight 60, and the target is 82%.
Calculation: Weighted average = (76 × 40 + 84 × 60) ÷ 100 = (3,040 + 5,040) ÷ 100 = 80.8%. Exam 2 needed = [82 × 100 − 76 × 40] ÷ 60 = 86%.
Result: The entered scores produce an 80.8% weighted average; an 86% second-exam score would be needed for 82% overall.
That is the exact title in the supplied master list. The implemented purpose is comparing and combining two exams.
No. Only their ratio matters.
The simple average treats both exams equally, while the weighted average gives more influence to the larger weight.
Convert each exam to a percentage first, especially when the exams have different maximum points.
The target cannot be reached with the entered first score and weights unless bonus points or another adjustment is available.
