$('li').eq(2).prev().prev();

This is the correct answer

index.html 
<!DOCTYPE html>
<html lang="en">
<head>
    <title>Document</title>

<body>
  <h2>Student List</h2>

  <ul class="student-list">

HI Jeremy Freedman

I'm not sure what you mean by "Incorrect"?

The answer to the challenge should only have one line of code. If you copy the two lines you have provided as the "correct answer" the challenge fails as it should because your code provided is in fact incorrect.

The first tasks asks you to select the list and the second task asks to transverse the list. This will all be done with one line of code, not two.

You should notice that just below the instructions for the tasks is an Important message regarding the challenge:

Important: In each task of this code challenge, the code you write should be added to the code from the previous task.

So, the second task is added onto the first task, so one line of code is correct, not two.

Hope that helps clear up why yours is actually not correct.
