Not sure where is the problem

Here's the question: Update the widget function to work with the new num_courses settings field. Assign the 'num_courses' of the instance to a variable named num_courses. Then require a file named widget-front-end.php in the inc folder.

And here's my code:

function widget( $args, $instance ) {
    extract( $args );
    $title = apply_filters( 'widget_title' , $instance['title'] );
    $num_courses = apply_filters( 'widget_title',  $instance['num_courses'] );
    require('inc/widget-front-end.php');
}

Try simplifying it. It doesn't ask to apply any filters to the num_courses so you should be able to just assign the num_courses instance directly to the num_courses variable.
