Hi @luigi_foll ,

You have this in your `get_average` function ...

``tests=average(students["tests"])``

The name `students` in undefined there. You probably intended to do this instead ...

``tests=average(student["tests"])``

hi @geomaticmashups,
this was the problem...thank you!!!

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

Im getting this error from codeacademy indeed there is no error in the console....
But the scores are perfectly fine, I doubt why get_class_average is taking alice as an argument where in it is taking the results list and has produced the correct result to the console....
