He's not doing his job, so why should he keep it? The man from what I've seen from your posts really as no business teaching students this subject plus is not keeping up with the most minimum standards they hold teachers at my 2year college.

You and the rest of the class did not get the class you paid for and the dean should be aware of this. You deserve your money back or the chance to take the class with again competent teacher.

Sorry if I got ranty but teachers not doing their jobs gets to me bigtime.
