Why is my code incorrect, I have tried using different forums and I still have not found an answer.

My error returns: Oops, try again. get_class_average([lloyd]) returned 91.15 instead of 80.55 as expected...

Referring to the passage at the very bottom, that is required to pass this section:

students = [alice, lloyd, tyler]

results = []

def get_class_average(student):

for student in students:

results.append(get_average(student))

return average(results)

```
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]
