I'm going to guess your issue is with the "fill in the blank" question: 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?

Here's a few hints:

  • remember to precede the function name with "document" ("document.querySelectorAll")
  • the argument goes inside parentheses after the function name
  • literal strings should be enclosed in quotes
  • in a selector for a class, the class name should be preceded by a period (".")
