I would seriously not recommend the AA. I had 19 lessons with my instructor and I had never passed traffic lights, been on a main road or a 'real' round about. I leant hardly anything. The repetition of each lesson meant I actually never moved over all the minor mistakes beginners should be able to overcome within the first 5 lessons.
My lessons mainly consisted of HIM driving, not me, so even at 19 lessons I STILL couldn't break correctly, take off correctly, turn corners and T junctions. Basically everything.
My instructor told me the reason for the slow place of lessons was that this was the 'safe way to learn'. However, it is of course not, he only wanted to drag out of me as much money as possible.
I should also add that this slow pace was not just because I am a terrible driver. Today I had my first lesson with an independent instructor and guess what? I have learnt MORE in that one lesson than I did before, and I actually drove for the entire lesson, which didn't happen with the AA until about my 17th lesson.
