Hi @hibachenni22 !

Pay attention to the error messages you are getting in the console

the error message is this

ReferenceError: score is not defined

You haven’t defined score here.

so you can’t use it. Also remember that the function expects an array of scores. not just one score

you need to use the parameters they gave you here

pick the parameter that makes the most sense to use there and replace score

once you fix that, then you need to fix this issue here too

score is not defined there either

again, you need to use the parameters given to you here

that is what is available to you.

you have the same issue here

you can’t use score there either.

you need to use one of the parameters from the function here

make sure to test your code along the way.
that is why the console statement is there for you so you can see what is going on with your code

once you fix those issues, then you need to fix the spacing issues mentioned.

this is what your code prints currently

Class average:71.7.Your grade:F.You failed the course.

you have spacing issues you need to fix

lastly, the function says to return the string not print it

once you fix all of those things, then it will pass

hope that helps
