    I would, yes.  Very basically:

database.tutors:
    id INT(8) NOT NULL auto_increment
    f_name VARCHAR(32)
    l_name VARCHAR(32)

database.courses
    id INT(8) NOT NULL auto_increment
    class_name VARCHAR(90)
    class_description MEDIUMTEXT

database.course_tutors
    id INT(8) NOT NULL auto_increment
    tutor_id INT(8)
    course_id INT(8)


    Then just run the query you want based on the following example:

<?php
// Database includes, etc....
$sql  = "SELECT course_name,course_description FROM courses WHERE id ";
$sql .= "IN (SELECT course_id FROM course_tutors WHERE tutor_id=";
$sql .= "'".mysql_real_escape_string($_GET['tutor_id'])."')";
$result = mysql_query($sql);
while($row = mysql_fetch_array($result)) {
    echo "Class: ".$row['course_name']."<br />\n";
    echo "Description: ".$row['course_description']."<br />\n";
}
?>

    You can also use JOINs and so forth, of course, but a simple
WHERE/IN should be fine.
