If your final exam is worth W%, your current grade counts for (100 − W)%. The required final score is calculated using: Required = (Target − Current × (1 − W)) / W. This tool is for quick planning; always follow your syllabus grading rules if they differ.
Find the score you need on a final exam to hit a target overall grade.
need = (target − current×(1−W)) ÷ W (with W as a fraction).
