How the formula works
Your final grade is a weighted average: (current grade × (1 − final weight)) + (final score × final weight). Solve for the final score and you get the formula in the box.
Example: you have an 84% and the final is worth 25%. For a 90% overall you need (90 − 84 × 0.75) ÷ 0.25 = 108% — not possible without extra credit. For an 80% (B) you need just 68%.
Where to find the final’s weight
Check your syllabus or course page — it usually lists how much each category counts. Then plan your study time with the GPA calculator in mind.
