Example: Final Grade Calculation

Let’s say a student has the following grades for a course:

AssignmentWeightGrade (%)
Midterm Exam30%78
Final Project25%90
Final Exam25%88

To calculate the final grade:

  • Homework: 85 x 0.20 = 17
  • Midterm Exam: 78 x 0.30 = 23.4
  • Final Project: 90 x 0.25 = 22.5
  • Final Exam: 88 x 0.25 = 22

Final Grade: ( 17 + 23.4 + 22.5 + 22 = 84.9 )
The final grade is 84.9, which corresponds to a C.
