# Add your function below!

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

Thanks for help!

Hi @whoray,

This statement should be outside the `get_class_average` function ...

``students = [lloyd, alice, tyler]``

Otherwise, it overwrites the `students` parameter, defeating its purpose, which is to enable any user of the `get_class_average` function, including Codecademy's submission correctness test (SCT), to pass any `list` of student dictionaries to the function.

Thanks a lot!
