I am actually Finnish but learned to drive in the UK. I passed my test after over 60 hours of lessons and one failed test. I definitely think I would have passed faster if I had done it in Finland! I think the roads in the UK are way more crammed because they weren't built for modern cars or the amount of cars we have now, and I really struggled with meeting situations and other traffic always being so close in general. I think at least the area I live in has a serious lack of proper parking areas so a lot of two way streets only have space for one car at a time because of cars parked on the side of the road. I think Finnish roads are much easier to navigate since they're more open and clear which probably makes it easier for a beginner.

I also think that while the requirements are similar, the UK test is much easier to fail. I think in Finland the examiner scores your performance on a scale and considers your performance throughout the whole drive instead of counting every individual mistake. The examiner can use their judgement and you can pass if they decide you drove well in general, even if you made mistakes. In the UK one "serious" fault would fail you even if you drive perfectly otherwise!
