How it works
Your course grade is a weighted average of the work you already have and the final exam. If the final is worth 30%, the other work counts for the remaining 70%. The calculator solves that average for the exam score that gives the course grade you want. It also shows the best grade you can still reach and what you would get with a zero.
The formula
Needed on the final = (target − current × (1 − weight)) ÷ weight
Here the weight is the value of the final as a decimal (30% is 0.30).
Worked example
You have 82%, the final is worth 30%, and you want 85% in the course.
- The work you have counts 70%: 82 × 0.70 = 57.4 points.
- You need 85 − 57.4 = 27.6 more points from the final.
- 27.6 ÷ 0.30 = 92% on the final.
The best grade you could reach is 57.4 + 30 = 87.4%.
Frequently asked questions
What do I need on my final exam to get an A?
Enter your current grade, how much the final is worth, and the grade you want for the course (for example 90). The calculator tells you the score you need on the final. If it is above 100, the grade can only be reached with extra credit.
Where do I find the weight of the final exam?
Look at your syllabus or the grading breakdown your teacher gave you. It is usually listed as a percentage, such as "final exam: 30%". If you are not sure, ask your teacher.
Is my current grade before or after the final?
Enter the grade you have so far, counting only the work that is not the final. The calculator then treats the final as the missing part of the course, worth the percentage you enter.
Why does it show 0% when I am already safe?
If your current grade already guarantees the course grade you want, even with a zero on the final, you do not need any points from the exam. The calculator shows 0% and "Already secured". Your teacher's rules, such as a required minimum on the final, may still apply.
