Not sure where I'm getting my syntax incorrect...var $newStudent = $('.student-list').append('<li>Sam Smith</li>')

Keeps asking if I called jQuery on '<li>Sam Smith</li>'

index.html 
<!DOCTYPE html>
<html lang="en">
<head>
    <title>Document</title>
</head>
<body>
    <h2>Student List</h2>

    <ul class="student-list">
        <li>James McAvoy</li>
        <li>Alena Holligan</li>
        <li>Wade Christensen</li>
        <li>Matt Krzyzynski</li>
    </ul>

    <script
    src="jquery-3.2.1.min.js"></script>
    <script src="app.js"></script>
</body>
</html>
app.js 
var $newStudent = $('.student-list').append('<li>Sam Smith</li>');

You're redefining the variable $newStudent. The task asks you to append this to the unordered list. Try:

var $newStudent=$('<li>Sam Smith</li>');
$('.student-list').append($newStudent);
