Took me 18 hours, passed first time with 2 minors. No previous driving experience. Although I still feel like I'm an awful driver 😂😂
It varies, depends on your instructor, how fast you pick things up and your confidence :)
I know the tests have changed recently though (in Wales, not sure about other places) and you now need to be able to follow a satnavs instructions instead of a person's. Which is harder than it sounds😢

I had 29 lessons before passing first time. This was 16 years ago tho xx

If you are a quick learner then you wont need as many. They have certain things they need to teach you for your test. Once you have gone through them then you basically just practise everything you know and your instructor will tell you when you are ready for your test. I had 10 lessons when I was 17 but then didn't have lessons again until I was pregnant (I was 23 then) and I had 10 lessons then my test and I passed first time x

It literally depends if you get the hang of it quickly or not ,once you have afew they can give you an estimate of how many they think youl need x

I’ve done 18 hours so far and still not ready for my driving test. It all depends on how quickly you pick it up
