@momobro1010,

-1
In the function names you should underscore's to separate the words
like

get_letter_grade
get_class_average

-2
In your get_average function
you are collecting the =average='s in the variable's homework, quizzes and test
( you should probably use tests )

You can then use these variables in your return statement
like

return 0.1*homework + 03*quizzes + 0.6*test
