Form not processing

Hi Guys

I am working on a plugin form. The problem is it does not set when the user submits it. Code below:

<?php
	if(isset($POST['course_form']))
	{
             echo "form set";
        } else {
             echo "form not set";
        }
?>

<form name="new_course_form" method="POST" action="https://localhost/wordpress/wp-admin/admin.php?page=mt-top-level-handle">
	<input type="hidden" name="course_form" id="course_form" />
        <input type="text" class="txtbox" name="course_title" id="course_title" />
        <input id="publish" class="button-primary" type="submit" value="Publish Course" name="publish"/>
<
</form>
