In your function `get_class_average`(), you need to make sure that you return outside of the for each loop, so `return` should be in line with `for`. Additionally, instead of making a new overwriting results, just return average(results).

#3

You need to include a global variable students that contains all your dictionaries because you are referring to it multiple times in your code,

`students = [lloyd, alice, tyler]`

This global variabe should be outside and before any of your functions.
