I've had two instructors. Had to abandon the first instructor after the 6th lesson because he had a heart condition, and strangely enough, I haven't heard of him since the January.. :/ On my first lesson he took me to a quiet road, told me the basics. Saw I knew how to do it, we carried to the streets. The rest of my 5 lessons with him we didn't do the rinse and repeat, just carried on. When I changed to my current instructor, I told her what I learned from my previous instructor, was taught all the remaining necessary manoeuvres on each lesson and now I'm basically just doing the same regular driving, to 'perfect them'. I never actually learnt from my instructor how to move off, turn and do the clutch control (apart from slow moving traffic on hills, which I could never understand how to do properly until she showed me and it's actually so simple :/). Long story short, from the two instructors I had, it's definitely how they see you, whether you understand. If they see you get it, they won't meddle with it and move on. Once you learn them all it really is just making them 'perfect'. So, I am sure that each lesson you will encounter the same manoeuvre you might have done 3 lessons earlier, even though they know you understand and do it well. They're trying to train that muscle memory of yours as well as being aware throughout the rest of your driving career. Like for example, I did bay parking today, which I have done only once and it was about 5 lessons ago. She saw me doing it well, she moved on. But parallel parking seems to be a bit of a weak point for me, even though I get it, I still seem to go too wide. Therefore, I've done that more than bay parking. So don't disheartened, it's normal. However, I've read that some try to cash grab you and not teach you anything, but I've also heard that it's rare.
