Here’s how to calculate final grades using Chatham County’s grading scale. Suppose a student has the following grades:

Midterm Exam78%
Final Exam88%

To find the final grade:

  1. Homework (20%): 85% x 0.20 = 17%
  2. Midterm Exam (30%): 78% x 0.30 = 23.4%
  3. Project (25%): 92% x 0.25 = 23%
  4. Final Exam (25%): 88% x 0.25 = 22%

Final Grade: 17% + 23.4% + 23% + 22% = 85.4% (B)
