work out grade percentages (1 Viewer)

[ehyde]

I was wondering how you worked out your grades, with maths some of the tests are worth different percentages, for example the first test was 10% but second was 30%, how do you calculate your overall percentage for that

Say you have these marks:

Test 1: 30/48
Test 2: 45/47
Test 3: 90/108

And say these are the weightings:

Test 1: 20%
Test 2: 30%
Test 3: 50%

Then to calculate your final mark:

30/48 x 0.2 + 45/47 x 0.3 + 90/108 x 0.5
