# Wrong number is returned on "Part of a whole"

<PLEASE USE THE FOLLOWING TEMPLATE TO HELP YOU CREATE A GREAT POST!>

Hi everyone. I’m experiancing a problem on the exercise “11. Student becomes the teacher - Part of a whole”
<Below this line, add a link to the EXACT exercise that you are stuck at.>

<In what way does your code behave incorrectly? Include ALL error messages.>
I get the error:
get_class_average([alice]) returned 83.8666666667 instead of 91.15 as expected
<What do you expect to happen instead?>
Not quite sure what’s causing the bug. Please help. Here’s my code:

```python

lloyd = {
“name”: “Lloyd”,
“homework”: [90.0, 97.0, 75.0, 92.0],
“quizzes”: [88.0, 40.0, 94.0],
“tests”: [75.0, 90.0]
}
alice = {
“name”: “Alice”,
“homework”: [100.0, 92.0, 98.0, 100.0],
“quizzes”: [82.0, 83.0, 91.0],
“tests”: [89.0, 97.0]
}
tyler = {
“name”: “Tyler”,
“homework”: [0.0, 87.0, 75.0, 22.0],
“quizzes”: [0.0, 75.0, 78.0],
“tests”: [100.0, 100.0]
}

def average(numbers):
total = sum(numbers)
total = float(total)

def get_average(student):
homework = average(student[“homework”]) * 0.1
quizzes = average(student[“quizzes”]) * 0.3
tests = average(student[“tests”]) * 0.6
return homework + quizzes + tests

if score >= 90:
return “A”
elif score >= 80:
return “B”
elif score >= 70:
return “C”
elif score >= 60:
return “D”
else:
return “F”

def get_class_average(students):
results =
school_class = [lloyd, alice, tyler]
for student in school_class:
results.append(get_average(student))
return average(results)

I’ll tell you how I found out what your error was. In the function that you’re writing in this part `get_class_average`, you get a list of students, then you completely dismiss that list, and then you loop trough your own list of students. Try using the list that you got as an input to the function instead
