Final Exam Score Calculator
Enter your current grade and target course grade to see what you need on the final exam.
Get Started
- Step 1: Enter your current course grade (find it in your LMS gradebook)
- Step 2: Enter the final exam weight (check your syllabus)
- Step 3: Set your target grade and see what you need
Final Grade = Current × (1 - Weight) + Exam × Weight
Weighted Average Formula
Understanding Final Exam Score Calculations
The Weighted Average Formula
Most courses calculate your final grade using a weighted average. This means different components of your grade (assignments, midterms, final exam) contribute different percentages to your overall grade.
Step-by-Step Example
Scenario: You have an 85% in the course, the final exam is worth 40%, and you want a 90% overall.
- Completed work weight: 100% - 40% = 60%
- Current weighted contribution: 85% x 0.60 = 51%
- Points needed from final: 90% - 51% = 39%
- Required final exam score: 39% / 0.40 = 97.5%
In this example, you would need a 97.5% on your final exam to achieve a 90% in the course.
When Is the Target Impossible?
If the calculator shows that you need more than 100% on the final exam, your target grade is mathematically impossible to achieve. This happens when:
- Your current grade is significantly below your target
- The final exam weight is too small to make up the difference
- Example: If you have a 70% and want a 95%, but the final is only worth 30%, even a perfect score won't be enough
Study Planning Tips
For Comfortable Targets (<70%)
You have some buffer room. Focus on understanding key concepts and avoid major mistakes. A steady review should be sufficient.
For Moderate Targets (70-85%)
Create a structured study plan. Focus on areas where you lost points during the semester. Practice with past exams if available.
For Challenging Targets (85-95%)
Intensive preparation needed. Consider office hours, study groups, and tutoring. Master all material thoroughly.
For Very High Targets (>95%)
This requires near-perfect performance. Focus on common exam patterns and potential trick questions. Consider if adjusting your target is realistic.
Important Limitations
This calculator provides an estimate based on the inputs you provide. Real grading may differ due to:
- Curves or grade adjustments applied by the instructor
- Extra credit opportunities
- Minimum exam thresholds (some courses require passing the final)
- Different calculation methods in your institution's LMS
- Dropped lowest scores or other special grading rules
Always confirm your course's specific grading policy with your syllabus or instructor.
