How to use the Grade Calculator

  1. Enter your current grade before the final exam.
  2. Enter the target grade and final exam weight from the syllabus.
  3. Compare the required score with the projected grade from your expected exam performance.
Formula

How the calculation works

Required final = [target − current(1 − weight)] ÷ weight

The current grade represents completed work and the final exam supplies the remaining course weight. The same weighted formula projects the course result from an expected exam score.

Worked example

Example calculation

With an 82% current grade and a final worth 30%, reaching 85% requires (85 − 82 × 0.70) ÷ 0.30 = 92%. Scoring 90% would project an 84.4% course grade.

How to interpret the result

A required score above 100% means the target is not reachable under the entered weights without extra credit. A score at or below zero means the target is already secured mathematically.

Important context

Notes and assumptions

  • The current grade correctly summarizes all completed weighted work.
  • The final exam is the only remaining graded component.
  • Extra credit, dropped scores, and category rules are excluded.
Common questions

Grade Calculator questions

What if the required score is over 100%?

The target is not reachable with the entered current grade and final weight unless extra credit or another rule applies.

Where do I find the final weight?

Use the percentage listed in the course syllabus or gradebook.

Does this calculate GPA?

No. Use the GPA Calculator to combine course grade points and credits.
