Question

My grade is 60% and I scored 80% on my summative that is worth 15% of my grade. What’s my grade now ?

Answer 1

To calculate your grade after the summative assessment, you can use the weighted average formula.

Let's assume your grade before the summative assessment is represented by G.

Given:
Grade before summative assessment: 60%
Grade on summative assessment: 80%
Weightage of summative assessment: 15%

We need to calculate the new grade (G') after incorporating the summative assessment score.

The formula for weighted average is:
G' = (G * (100% - weightage) + (summative grade * weightage))/100%

Substituting the given values:
G' = (60% * (100% - 15%) + 80% * 15%)/100%

Simplifying the equation:
G' = (60% * 85% + 80% * 15%)/100%
G' = (0.6 * 0.85 + 0.8 * 0.15)/100%
G' = (0.51 + 0.12)/100%
G' = 0.63/100%
G' = 0.63

Therefore, your grade after the summative assessment is 0.63, or 63%.
