He is scary when you first meet him and then when you have him for a while he is alright. You don't want to get on the wrong side of him. He is also quite emotional when you have had him for a while like one of my friends who was in his form group with me passed away an he started getting upset and kept her chair empty in the seating plan and shouted at anyone who sat in it. I didn't understand his maths lessons for two years then on the last week I completely got what he had been saying.
i think this rating is totally unfair, he is genuinely one of the best teachers i hav ever had, maybe a little scary, but a funny, entertaining guy and a great teacher. He was a big influence
