Good morning everyone!
If somone had a 66.5% as their overall grade, and a final is worth 10%, is it possible for that 66.5% to raise up to a 70%?
To see if it is possible, we can just say you aced your final, 100% and see if it exceeds 66.5%.
Your current grade is 66.5% and it represents 90% of your final grade.
If you aced your final, 100%, it will still represent 10% of your final grade.
\({0.665\cdot0.9+1\cdot0.1}=0.6985\)
You will get a final grade of 69.85% even if you aced your final.
It depends what your teacher rounds up by.
If he/she rounds up by whole number, you will get 70%.
If he/she rounds up by tenth, you will get 69.9%, oof.
If she doesn't round, you will get 69.85%.
I hope this helped,
Gavin
