The code bellow runs well and alice average is 91.15. I added some prints to see alice's average.

When running the code a get the following error message: Oops, try again. get_class_average([alice]) returned 83.8666666667 instead of 91.15 as expected

Any help?

```
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]

"quizzes": [0.0, 75.0, 78.0],

}
