what percent is the lowest A in the class... without that its impossible to determine what you will need to maintain an A in the class.
im going to guess 90% is lowest A
example: 100 points for class
80 for everything before final exam and 20 for exam
.95(80)=76
((76+x)/100)100=90%
76+x=90
14=x
14/20=56%
you need atleast a 70% on the test to maintain an A in the class(according to a 90% A scale)
