@bambifury They are usually recommended for those who want refresher courses so those that have already had lessons. Lots of people do not have access to a car for private practise.
Best thing I can recommend as my son passed his driving test last year is YouTube. There are lots of driving instructor videos. Start with the mechanics of the car, so understand what the clutch does and how to never stall the car. Then watch someone on their driving lessons again so you can pick up all the theory, there are driving instructors who have students they follow from day one. Off the top of my head, Ashley Neal, DGN Driving School, Clearview and Conquer Driving.
They also have lots of mock tests and voice over what they did well and what they should have done. You can learn a shed load of information for free before you get into a car. It includes what lane to be in, what you should be looking out for, that you should check all your mirrors before moving off if you have been sat at traffic lights, where to position your car for a right hand turn in a junction etc.
Ds did this and we watched lots of them together. He had 2 hour driving lessons at a time with a top rated instructor for £68 a time. The mock tests also show situations you might not come across locally on Clearview mock test the student tries to go through an ambulance gate of some sort. Never seen that round here.
The more theory you know, the easier it will be. We also watched a lot of dash cam videos of near misses to see what the potential hazards were, the fall into the same categories and you can pretty much guess it, bad emerge from a junction, cannot use a roundabout and in the wrong lane, overtakes on country lanes meaning someone is on your side of the road.
If you can just sit in a car, a friend or whatever just to feel the gears and learn that, that would help you too. I mean sit on their drive, put the clutch down and learn the gears. If you manage to practise in a car you can get insurance that is completely separate to the car owner's insurance, meaning should the worst happen and you bump the car it doesn't affect their car insurance. We used Veygo as did lots of MNetters.
