The nicest man ever. He lived for his students. I was the worst honours maths student ever but he kept pushing me & I got thru it. Brought us on best tour ever!

although this teacher is very popular, his teaching ability is extremely poor and his communication skills are equally bad. just being honest.

Fantastic teacher, I'd have had no hope passing honours LC without him. Excellent for applied maths too. Not too strict but has no problem controlling a class
