If I have a 60% in my class and I score a 80% on my summative that is worth 15% of my mark. What is my current grade afterwards?

Answer 1

To calculate your current grade after the summative, you would first find the weight of your existing grade and the weight of the summative.

Since your current grade is 60% and it is worth 85% (100% - 15%) of your total marks, the weight of your existing grade is 60% * 85% = 51%.

The summative is worth 15% of your total marks, which means its weight is 15%.

Next, you would calculate the weighted values of each grade.

For your existing grade: 60% * 51% = 30.6%
For the summative: 80% * 15% = 12%

Finally, you would add these weighted values together to find your new overall grade:

30.6% + 12% = 42.6%

Therefore, your new overall grade would be 42.6%.
