How to use this calculator
Enter your current grade before the exam, your target final grade, exam weight, and minimum passing grade.
The calculator estimates the exam score required to hit the target and flags when the goal is difficult or mathematically impossible.
What the result means
The result shows the score needed on the upcoming exam. A required score below 80% is manageable, 80% to 95% is challenging, and above 100% is impossible without extra credit.
Required exam score = (Target final grade - Current grade × Current weight) ÷ Exam weight
Current weight is calculated as 100% minus exam weight. This assumes the current grade represents all coursework before the exam.
