Keeps throwing up this error message and i can't for the life of me figure out why.
Oops, try again. get_class_average([alice]) resulted in an error: 'list' object has no attribute 'appened


As far as i can tell it should work fine. Can anyone tell me what I've done wrong.

results.appened(get_average(student))

should be append, not appened.
