As per the logic needed in the task, your code is incorrect. Let’s address the issues one by one.

If you want to calculate the average of the total scores, you already have the function to do that getAverage() then pass the totalScore parameter to the function.

Also, instead of consoling your values, return them using the return statement.

Thanks for telling me but they were asking to print out result as a sentence which is why I have tried it like this. tell me again if I didn’t get what u were explaining. thank you for telling me where I messed up.

The function should return a string representing a message to the student.

the function needs a return statement, it is written in the istructions that what is returned is the important thing
