Like I say I can't comment on the longer courses, but Darren who runs North East Tiling believes in efficiency in everything. The course length is what he deems efficient to deliver what you need, the rest is practice really.
You will have all the knowledge you need to go out and source work. The rest is up to you. Give him a ring and have a chat or speak to Tracey his wife. There nice people. Nows a good time to be a tiler in Scotland as apparently there is a shortage and you get better rates than in England so strike while the irons hot.
Oh and if you do get in touch tell them Eric recommended them to you.
Good luck
