hello mate .i done the nett course in january and thought it was quite good .have done two jobs since (one big one small) its not much but i also work fulltime as a forklift instructor. anyway i am happy to take my time at the moment and build up my knowledge .just had some cards printed and my best mates a plumber so see what happens.as for the course if you have a bit of tiling knowledge i think you could possibly go on to be a
tiler. but for people to turn up for a 4 day course thinking that they can walk away to set up straight away is probably unrealistic .
