Doing the manouvers can screw you up if youve got a few years of bad habits.

Making sure you use the handbrake when required, none of the using footbrake to hold it at the lights etc.

Anyone can do a 3 point turn and reverse round a corner its doing them in accordance with the "rules" thats easy to forget, ie correct clearance on major and minor road, reversing far enough back down minor road etc.

My parallel parking was shocking until i practised it as I park in a car park at home and at work so never need to do it!!!

I don't know what they teach with gears now but when I learnt to drive it was 4th gear at 30mph then when I did my driver training it was 3rd gear at 30mph for better control of engine/responseivness and car control.
