How this calculator works
The Grade Calculator computes a weighted average grade from multiple assignments, exams, or categories with different weights. Enter score 1 (%), weight 1 (%), and score 2 (%) to estimate final grade (%), total weight (%), and letter grade (numeric). The calculator updates instantly and adds a comparison table plus chart so you can test the sensitivity of the result before you use it in a decision.
