best teacher ever. when he tells you to go play games he is testing you to see if you do so or if you go study the course. if you go play games you failed the test.
Mr Duff is totally awsome. dont have him this year. but he still has a laugh with me. if it wsnt for him i wouldnt have passed computing :) if you want to learn he will teach you but i you dont then he wont waste his time on you. its your own loss.
Wait A Minute....Mr Duff Rawks. Yes Sure He Gives You Free Periods But Everyone Needs A Break Once In A While.And If You Didnt Learn Anything In His Class Then It Is Your Own Fault....x Ly
not a good teacher shows us how to open up the internet then he just sits and plays solitaire
Duff is a great teacher. You guys proablly never learn't anything because he doesn't waste time on people that don't want to learn.
nah c'mon, comments bit harsh like! Great teacher!!!!!
Not a very good teacher. Taught us hardly anything. I only learnt bout computin' when we got moved teachers.
