Question

I am at a 72% C in math I got a 12.5 out of 20 on a test will that bring me down a letter grade?

test are worth 90% of total grade

HW is worth 10% of total grade

Answer 1

12.5/20 = 62.5/100 = 62.5%

IF 72 is HW worth 10% take a weighted average

.1(72) + .9(62.5) = 7.2 + 56.25 = 63.45 = 63.45%

You're dropping from a C to a D
