I learned that in Finnish schools, students are graded not just by their knowledge, but also by the amount of work

I think that I should insert the disclaimer that although this was my experience, it may not be true everywhere: Finnish schoolteachers are also given a large amount of autonomy in exactly how they want to organize and grade their lessons, so it's conceivable that other schools might have done things differently. Also, things may have changed since the time that I was in primary school.

That said, I would be very happy to see you improving the education in Finland. :D
