When your current grade represents completed course work and the final has a known weight, you can project the course result with a weighted average.
If your current grade is 84%, the final is worth 30%, and you earn 92% on it, the projection is 84 × 0.70 + 92 × 0.30 = 86.4%.
This calculation assumes the displayed current grade represents the completed portion of the course. A gradebook may handle missing work, category weights, replacement scores, or extra credit differently.
Check your syllabus — most courses state the final exam's percentage of the total grade up front. If it isn't listed, ask your instructor before relying on a projected grade.
This basic formula assumes a single remaining final. If you have several remaining assessments (a final exam and a final project, for example), calculate each one's weighted contribution separately and add them together.
No — a projected grade is an estimate based on the numbers you enter. Your official grade depends on how your instructor's gradebook handles rounding, dropped scores, extra credit, and any other course-specific policies.
