Point1.
You forgot to create a list `students` containing tyler,alice and lloyd.
`students = [lloyd, alice, tyler]`
Define it before `get_class_average()` function.

Point2.

``````for student in students:
results.append(get_average(student))``````

Make sure that this line of code is indented properly.
