I'd try and get something sorted pretty quickly anyhow, as it's getting to the time where instructors will start getting fully booked up, what with summer not that far away.
I saw the layout of the new test and spoke with one of the test examiners and they said that it wasn't that much more difficult than the current one.
If you can't do the u-turn on the off-road part then you shouldn't really be riding, no kerbs and it's really wide.
