If that is your attitude, why are you on a forum asking for advice?
If you really believe CBT and the mods are that easy then just go and do them, then you can come back and tell us all how fantastic you were.
On my CBT I did the whole day. I did not need to as I had been riding for years before it, but a licence cock up meant I lost motorcycle entitlement so effectively I was classed as a learner, but the instructor didn't want to go out on the roads with just the 2 complete novices he had (he put me up front so they could follow me and he could keep an eye on them from the rear)
Watching all the videos in the world will not teach you clutch control when moving at walking pace, or how to feather the rear brake - you need to actually be on a bike for that and not all bikes are the same. A young lad I knew passed his tests and bought a Aprilia race replica 125, and unless you hit about 6000rpm before releasing the clutch the damn thing stalled (I know, I tried the bloody thing out at work one day).
So, my advice, stop buggering about on here and go get the tests done
