grade will be determined on a weighted average as follows:

homework 30%

midterms (3 of them) 50%

final 20%

NOTE : I MUST AVERAGE AT LEASE 65% ON THE 3 MIDTERMS AND FINAL IN ORDER TO GET AN A,B OR C (OTHER WISE I GET D OR F TEACHER SAYS!)

TOTAL PERCENTAGE :

55-69% D

70-79% C

80-89% B

90-100% A

C (74%)

(65*0.2 + 65*0.5 + 95*0.3) = 74.  That's a C.
