Please provide some intuitive explaination to why this code is not working? get_class_average([alice]) returned 83.8666666667 instead of 91.15 as expected

Did you mean to write students?

yeah, just experimenting a bit:)

That should be on your time, not ours. When posting a question be sure your code is not experimental. This disrupts other learners. Once you complete a module (all lessons) you are free to go back through it and review and experiment all you wish. But make sure if you post a question about your experiment it is not in the topic forum, but in the Corner Bar.
