What if i have a 64% and i fail the exam, which is worth 20%. what mark will i have after?

Question

and i failed with a 42.

Answer 1

If your average before was 64, then that 64 was 80% of your grade. The 42 you recieved is 20% of your grade. (.8 x 64) + (.2 x 42) = 59.6, or a 60, as a final average.

Answer 2

yep 59.6    hope you did your teacher some favors

Answer 3
