Calculate Your Required Final Exam Score

How to Calculate Final Grade

The final grade calculation is based on a simple formula that takes into account your current grade and the weight of your final exam. Understanding this calculation helps you determine exactly what score you need on your final exam to achieve your desired grade.

Formula Explained

The formula for calculating your final grade is:

Final Grade = (Current Grade × (100 - Exam Weight) + Final Exam Score × Exam Weight) ÷ 100

To find the required final exam score, we rearrange this formula:

Required Final Exam Score = (Desired Final Grade - (Current Grade × (100 - Exam Weight) ÷ 100)) ÷ (Exam Weight ÷ 100)

Step-by-Step Calculation Process

  1. Multiply your current grade by the percentage of your grade that is not the final exam (100 - Exam Weight)
  2. Subtract this value from your desired final grade
  3. Divide the result by the exam weight percentage (converted to decimal)
  4. The result is the score you need on your final exam

Calculation Examples

Example 1: Passing with a B

Current Grade: 75%

Final Exam Weight: 40%

Desired Final Grade: 80% (B)

Required Final Exam Score: 87.5%

Step-by-Step Calculation:

1. 75 × (100 - 40) ÷ 100 = 75 × 0.6 = 45

2. 80 - 45 = 35

3. 35 ÷ 0.4 = 87.5

Therefore, you need to score 87.5% on your final exam to achieve a B (80%) in the course.

Example 2: Maintaining an A

Current Grade: 92%

Final Exam Weight: 30%

Desired Final Grade: 90% (A)

Required Final Exam Score: 84%

Step-by-Step Calculation:

1. 92 × (100 - 30) ÷ 100 = 92 × 0.7 = 64.4

2. 90 - 64.4 = 25.6

3. 25.6 ÷ 0.3 = 84

Therefore, you need to score 84% on your final exam to maintain an A (90%) in the course.

Example 3: Improving to Pass

Current Grade: 65%

Final Exam Weight: 50%

Desired Final Grade: 70% (C)

Required Final Exam Score: 75%

Step-by-Step Calculation:

1. 65 × (100 - 50) ÷ 100 = 65 × 0.5 = 32.5

2. 70 - 32.5 = 37.5

3. 37.5 ÷ 0.5 = 75

Therefore, you need to score 75% on your final exam to improve to a C (70%) in the course.

Important Notes

  • If the required final exam score is above 100%, it means it's mathematically impossible to achieve your desired grade with your current grade.
  • The higher your current grade, the lower the score you need on your final exam to maintain or improve your grade.
  • The higher the exam weight, the more impact your final exam will have on your overall grade.
  • Always check with your instructor about the exact grading policy for your course, as some may have additional requirements.
