How the Calculation Works

The formula used is:$$\text{Required Exam Score} = \frac{\text{Target Grade} – (1 – w) \times \text{Current Grade}}{w}$$Required Exam Score=wTarget Grade−(1−w)×Current Grade​

Where:

• w = final exam weight (as a decimal)
• Current Grade = your grade before the exam
• Target Grade = final grade you want in the class

✔ Example Calculation

Current grade: 78
Final exam weight: 40% (0.40)
Target grade: 85$$\text{Required} = \frac{85 – (1 – 0.40)\times78}{0.40}$$Required=0.4085−(1−0.40)×78​ $$\text{Required} \approx 94.33\%$$Required≈94.33%

Meaning:
You would need about 94.33% on your final exam to earn an 85% overall.
