Monsieur Hirsch

He explains concepts with patience and accuracy, even though you didn't necessarily reviewed the course that you had to prepare for the D day. He gives a chances to everyone to learn something, even the least interested person in the subject. He takes concrete examples on various media supports. He doesn't care about the grade you'll get but only about what you'll learn at the end of the course. He requires as much attention as he gives, so you can't be on your phone while he talks.
