Blimey.
The lad I was with was almost a fail as was very sketchy doing the manoeuvres (that's how you spell it, really?) the instructor said to me "No way is he going on the road unless he picks up". He just about scraped through but these kids have no basic highway code understanding, for example, he did not understand "right of way" and was confused at traffic lights/junctions. Just a young kid who had rode his mates bike in a field probably thinking he "knew how to ride".
I cannot talk, my uturns were shocking
I do not see why the theory is not a perquisite for CBT seeing as you are riding alone with nobody to advise you.
