he is a exellent maths and science teacher
Mr Cohen is an excellent teacher and knows everything. He feedback to our class was very good.
expects you to know everything, plays with your mind
Mr.Cohen expects his pupils to do all theory at home as school is just for him to do practical activities for his own amusement or to show of his latest gadgets and don't forget his trademark walk
Looks like he hasn't changed his ways in the more than 10 years since I had the misfortune of being in his class. Time and time again his actions proved his unsuitability for the teaching profession.
