Error Message:
Oops, try again. get_class_average([alice]) returned 83.8666666667 instead of 91.15 as expected

lloyd = {

    "homework": [90.0, 97.0, 75.0, 92.0],
    "quizzes": [88.0, 40.0, 94.0],
    "tests": [75.0, 90.0]

# Add your function below!
def average(numbers):
    sum(numbers)    
    total = sum(numbers)
    total = float(total) / len(numbers)
    return total
    
def get_average(student):
    homework = average(student["homework"])
    quizzes = average(student["quizzes"])
    tests = average(student["tests"])
    return 0.1 * homework + 0.3 * quizzes + 0.6 * tests

    if score >= 90:
        return "A"
    elif score >= 80:

    elif score >=70:
        return "C"
    elif score >= 60:
        return "D"
    else:
        return "F"
        

def get_class_average(student):
    results = []
    
    for student in students:
        results.append(get_average(student))
    return average(results)

Thanks in advance!
