that will be me then you can only teach a good student if they are willing to learn and listen. you learn alot quicker if you listen. my student(xr-stu) was a very good student lol. as said its hard to learn in a classroom as in real life every job is different and troubles crop up every where. as you have been a plasterer i would say the course is a waste of time as you seem to know the ins and outs of tiling already. save your dosh and buy a smart little van instead. go for it as im sure if you need any help just pm me or stu and im sure if we can help we will.
