He is a very smart teacher but teaches bluntly. He has no fun with teaching. The labs and experiments are very boring and you have to write a paper each time. If you ask him questions he will explain but if you don't it is really hard to understand the concepts. If you are willing to put in work your fine. And the stamps hey should be worth more points considering there is a lot of homework within them. Also the classroom is very boring needs some decorating after 40 years of the same thing.
Amazingly great teacher that knows everything and can tie anything to a story.
