# Student Becomes the Teacher #11 Problem

<In what way does your code behave incorrectly? Include ALL error messages.>
Hello,

I am not quite sure where to begin looking for the error, when I try to run the code I get the error message:

Oops, try again. get_class_average([alice, lloyd]) returned 91.15 instead of 85.85 as expected
<What do you expect to happen instead?>
It should be working I am pretty sure, yet it’s giving the wrong average.

```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)
total /= len(numbers)

def get_average(student):
homework = average(student[“homework”])
quizzes = average(student[“quizzes”])
tests = average(student[“tests”])

``````homework *= 0.1
quizzes *= 0.3
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”
