What equation do I use to find out what I need to get on my exam to pass my class. I have a 65.9% and the exam is 20% of my grade....if you need any additional information let me know..... also a passing grade is 59.5

say you took 5 tests, 20% of which or 1 is this final
.659 (4)+ x (1) = .595 (5)
2.636 + x = 2.975
x = .339 or 33.9 % 
okay so that means that the lowest grade that i can get on my exam is a 33.9?

Yes
