i do know how to conduct RT and know all of the aspects of it, its just the fact that i didnt know what they would ask me.
just like in A level exams, u could know all about the subject but have no idea what they would ask!
regards to why i think its a waste of time, is that i been using RT all the way through my training and indeed within the skills test. therefore i think that would have shown i am proficient with RT. Paying extra money on top of the skills test is where the waste of money comes from
