Hi there,

For some reason this code gets accepted, however it does not give the correct letters. For instance for Lloyd it get's an weighted average of 80.50 but he get's an "A" any way. Even though this is privilaged to people of 90% and up.

Does anybody know what I'm doing wrong?

Thanks, Sjors
