It's actually taken me a lot longer than I first anticipated. I took 5 days of training back in February, which included a test, which I failed. That knocked my confidence a little and I gave it a break, and before I realised it was 5 months later.
Roll on to last month, when I had one more day of training to refresh my memory and do another test... which I failed AGAIN!
Both times the failure was on the u-turn in the road maneuver. I almost lost balance and my foot automatically went down, which is an instant fail. First time was fair enough, I just wasn't very good at them. The second time around it was pure nerves as I knew it was what failed me the first time.
This time, no problems. Not a single minor fault, just a nice ride in the rain and got the u-turn nailed.
Apart from the stupid u-turn the test is not hard, especially if you're already a driver or you've had experience on the road with a moped or something.
The test is going to become slightly different in the next few months - they will be doing all the maneuvers in controlled conditions on the test centre premises, followed by a road ride, rather than just the road ride they have now.
I like to think it's made me a better driver too as I'm now MUCH more aware of bikers on the road.
