Oops, try again. get_class_average([alice]) returned 83.8666666667 instead of 91.15 as expected...

Below are the results I get when finding the individual student's average and then returning the class average. I'm not sure where I went wrong with my code.

[80.55]

[80.55, 91.14999999999999]

[80.55, 91.14999999999999, 79.9]

83.8666666667

Any suggestions, hints or clues ?

Thanks peeps!
