Had him way back in eary 90's in Taranaki. Good to see hes still going strong. How did he really know the location of every single town in the world, no matter how small. Still havn't figured it out.

This man is a head case & may need the attention of a psychotherapist. As a teacher he thinks he is the man, for some reason he thinks he has made it in the world by being a teacher.

Left CBHS now, but he was undoubtedly the best teacher I ever had. Surprisingly easy to get on with if you took the time to talk with him. Always told some good yarns.

Actually, a very nice guy. Definately knows how do get the best out of his students, and is very dedicated to ensuring everyone achieves the best they can. Strict, but absolutely fair -- If you show him some respect and put in some work, he will help you and support you, no matter how smart you are! Sign of a very good teacher, one of the best in the school! There aren't enough like him around anymore!

An exceptional maths teacher who explains things thoroughly and if he can't work out a problem will always come back the next day with a solution. Rather arrogant at times but certainly a great teacher.

Hmmmmm, good teacher, i think. I just feel sorry for him cause it doesn't look like he's a happy chap. First day back he told my class we wern't as smart as we thought we were and that we should get over ourselves haha

e is possibly the teacher in the history of CBHS. He is certainly the best I have ever had. Once you get past how hard he is on you and all the the work he sets you will find that you learn a lot.

well let me just start to talk about the expectations he sets for his students. Armstrong is completely obsessed with maths and probably gets pleasure from it at home. He expects students to get amazing grades when it is obviously impossible for them to achieve this. Hes a good teacher but maybe..... just maybe he is TOO good! I wonder what he does in his spare time. Like i wonder if he does maths at the movies and wat not..... oh well, stick at it army man!
