Grade Calculator
Compute a weighted grade or find what you need on the final for a target mark.
Your grade is 81% (B).
Letter scale: A≥90, B≥80, C≥70, D≥60, F<60 (schools may differ).
How it works
Weighted percent = Σ(score × weight) ÷ Σ(weights). Letters use A≥90, B≥80, C≥70, D≥60, F<60.
Final needed: target = current×(1−w) + final×w, solved for final.
