What this page cannot tell you
This assumes your current grade already counts everything except the final, and that the course uses a simple weighted average. Curves, dropped scores, points-based grading and minimum-score rules on the final change the answer; check the syllabus.
How to work out the score you need on a final
- Enter your current grade. Your percentage before the final.
- Enter the grade you want. For example 90 for an A on many scales.
- Enter the final's weight. From the syllabus, as a percentage.
- Read the score needed. Plus your final grade for a range of exam scores.
10 reasons students check what they need on a final

Teacher explanations
A teacher shows students how weighting works.
How the needed score is calculated
With the final worth w (as a fraction), your course grade = current × (1 − w) + final × w. Solving for the final: needed = (target − current × (1 − w)) ÷ w.
The table shows your course grade for final scores from 50% to 100%.
Limits: this assumes your current grade already reflects everything except the final and that the course uses a weighted average. Curves, dropped scores, points-based grading and minimum final-exam rules change the answer.
Frequently asked questions
What do I need on my final to get an A?
Enter your current grade, 90 as the target and the final's weight; the page shows the score.
How do I calculate my final grade?
Current grade × (1 − final weight) + final score × final weight.
What if I need more than 100%?
The target cannot be reached without extra credit.
Where do I find the final's weight?
In the course syllabus.
Does it work for points-based classes?
Convert your points to percentages first; weighting by points works differently.
What if my current grade includes the final?
Use your grade before the final for this calculation.
