I did one two years ago as well.
I did classroom in morning and driving ith instructor in afternoon. (I don't think they do instructor bit anymore)
It wasn't much fun tbh, although learnt what 'dual carriageway' means for speed limits.
Me and another guy did the during bit and the instructor gave us a debrief after and said 'both your driving sessions were very good and I can't see how you managed to drift above the speed limit and get persecuted as you are both as drivers very aware"
Bloody fool!
