He does his job well which is to teach chemistry. Well organized & knows his stuff. He doesn't give a show & doesn't tolerate people chatting, so many students find that "boring".
Moche moche moche. Toujours le même ton de voix! Super ennuyant.
I found him just fine! To be quite honest, he wasn't as bad as people had warned me about! I managed to get a good enough science grade, without dreading class.
