querySelectorAll question, getting the quiz wrong and don't know why?

I'm not sure what's going wrong here. Can't finish the quiz cause you need all 4 questions right. I'm quite sure i'm getting this right though so this is really confusing me, the question is:

"How would you use querySelectorAll to obtain a reference to all elements in a document with the class student-info and assign it to the constant studentInfo?"

They give you this piece of code "const studentInfo = _______________ "

my answer is:

const studentInfo = querySelectorAll('.student-info')

Really not seeing what im doing wrong here so any help would be appreciated

You are forgetting about document. The answer to the Quiz is: document.querySelectorAll('.student-info')

It's an easy thing to forget, but it's important to remember because querySelectorAll by itself won't get you anywhere since it belongs to the document object.
