I did as the instructions ask:

1. First, make an empty list called results.

2. For each student item in the class list, calculate get_average(student) and then call results.append() with that result.

3. Finally, return the result of calling average() with results.

The error I get is that the average of all the scores is incorrect. I get 83.86, but it is saying I should get 91.15.

I have a theory of why this is, but I feel like I would have to veer off what the instructions are asking of me to complete.

I am thinking that if I combine the keys(homework, quizzes, test) of each student then do the "get_average" function of that list then i'd be getting the 91.15 its saying I should get. I don't think that's what the instructions are asking of me though.. so I want to see how i'm following the instructions wrong.
