What wrong with my answer?

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?

Someone asked the exact same thing on Tuesday (searching the forum history can be useful!).

Remember that class selectors start with a period, so:

const studentInfo = document.querySelectorAll(".student-info");
