Is it supposed to be document.querySelectorAll?

I am confused on how this is supposed to look. Is it that or some form of document.querySelectorAll('student-info');

You forgot the point "." in front of the student-info it´s a class :)

It is indeed a variation of document.querySelectorAll('student-info').

The querySelector and querySelectorAll method takes a CSS selector as their argument. In CSS you select classes by typing a period and then the name of the class. So to select the student-info class the code would look like this:

document.querySelectorAll('.student-info');

And that it the answer to the quiz. Knowing basic CSS selectors is quite handy even if you mainly do JS development since they are quite useful for selecting elements.
