Oops, try again. get_class_average([alice]) returned 89.75 instead of 91.15 as expected

Check your code. It's "homework*0.1+quizzes*0.3+tests*0.6". You've calculated it as: "0.1*tests + 0.3*homework + 0.6*quizzes"

Thanks, fixed it. I must of tried it like that once and it kept defaulting to that even when I clicked reset code as when I go back a few lessons and look I had this originally

return 0.1 * average(student["homework"]) + 0.3 * average(student["quizzes"]) + 0.6 * average(student["tests"])
