South Korea vs Finland

Hello everyone.
Today our teacher has focused the lesson in this question: South Korea and Finland: two nations that have completely opposite approaches whose students consistently rank on the top of the world. How is that possible?
Before answered it, we watched a video and, after watched it we have to work in the question I put above.
So, in South Korea students spend many hours at school because they want to have a very good formation. For example children get up very early, do physical exercise and have a very healthy breakfast, because parents think a healthy life helps children in their stududies. Also,
In addition, children go to extra lessons after school and parents spend a lot of money, so children think they have the responsability of studying hard.
In Finland students spend less time in school but there, teaching is a very respected profession, there are great teachers. Teachers have to study very hard to work in Finland, it's very difficult to work there if you are not qualified. But on th other hand. they can teach with more autonomy.
