How to Calculate Grade — Formula, Examples & Guide

learn.whatIsHeading

A grade calculator computes your overall course grade from individual assessment scores weighted by their contribution to the final grade. Understanding weighted averages helps students know exactly where they stand and what score they need on remaining assessments.

公式

Weighted grade = Σ(score × weight) / Σ(weights)

分步指南

1Weighted grade = Σ(score × weight) / Σ(weights)
2All weights must sum to 100% for a complete grade calculation
3To find needed score: rearrange — needed = (target − current_weighted_sum) / remaining_weight

例题解析

输入

Exams 60% (scored 72%) + Coursework 40% (scored 85%)

结果

77.2% overall

0.6×72 + 0.4×85 = 43.2 + 34 = 77.2%

输入

Need 70% overall, have 65% with 40% of grade remaining

结果

Need 77.5% on remaining work

(70 − 65×0.6) / 0.4 = (70−39)/0.4 = 77.5%
