I dont know what i am doing wrong!!

This is starting to get really frustrating, I am doing exactly as the instructor

index.html
<!DOCTYPE html>
<html lang="en">
<head>
    <title>Document</title>
    <link rel="stylesheet" href="style.css">
</head>
<body>
    <button type="submit" class="submit-btn">Submit If You Can</button>

    <script
    src="jquery-3.2.1.min.js"></script>
    <script src="app.js"></script>
</body>
</html>
app.js
const $submit = $('.submit-btn'); 

$submit.attr('disabled', true );

$submit.addClass('disabled');

Your code isn't technically wrong but what the challenge wants you to do is chain both jQuery methods together like this:

$submit.attr('disabled', true ).addClass('disabled');

This is a very common thing to see in jQuery code so my guess is that the challenge is trying to help familiarize you with this way of thinking.
