How It Works

How to Calculate Your Final Grade

Your final grade is a weighted combination of coursework and the final exam.

Formula

Final Grade = (Coursework Grade x Coursework Weight) + (Exam Grade x Exam Weight)

Where Exam Weight = 100% - Coursework Weight.

Worked Example

You have an 88% in coursework (worth 70%) and score 78% on the final exam (worth 30%).

current_grade = 88course_weight = 70final_exam_grade = 78
  1. 01Coursework contribution: 88 x 0.70 = 61.6
  2. 02Final exam weight: 100% - 70% = 30%
  3. 03Final exam contribution: 78 x 0.30 = 23.4
  4. 04Final grade: 61.6 + 23.4 = 85.0%

Frequently Asked Questions

How much can a final exam change my grade?

It depends on the exam weight. A 30% final can move your grade up to 30 points. The higher the weight, the more impact.

What if my final exam is cumulative?

This calculator works regardless. The weight assigned in the syllabus determines the impact on your final grade.

Should I include the final exam in my current grade?

No. Enter your grade before the final. The calculator adds the final exam separately based on its weight.
