How to Calculate Your Final Exam Score

This calculator determines the minimum score you need on your final exam by using the weights of your current grade and the final exam. It works backward from your desired grade to tell you what you need to achieve on the last assessment.

Inputs Explained

  • Current Grade (%): Your grade in the class before taking the final exam.
  • Desired Grade (%): The final grade you want to achieve in the course.
  • Final Exam Weight (%): How much the final exam counts toward your overall course grade (e.g., 20%, 30%, 50%).

Example

Let's say your current grade is 85%, you want to get a 90% in the class, and the final exam is worth 20% of your grade.

The calculator determines that the 85% you currently have is worth 80% of your final grade (since 100% - 20% = 80%).

To find the score you need, it calculates that you must score 110% on the final.

The calculator will then tell you that achieving a 90% is not possible with these inputs.

Tips & Important Notes

  • Double-check the final exam weight with your instructor or syllabus, as this is the most critical input.
  • Use the "Detailed Grade Breakdown" in the advanced options for a more accurate "Current Grade" if you have all your component scores.
  • If the calculator says you need a score over 100%, you may need to adjust your desired grade or focus on extra credit opportunities.
