Let me add my perspective on the Finnish education system. I have had one child go through the system, and the other one is still in school. Since we have all probably heard the positives, let me put down some things that are not so apparent.
Up until students get to 7th grade, students have only one teacher (homeroom teacher) for most subjects and quite often the same teacher continues with the students to the next academic year until they reach 7th grade. The teacher has a lot of freedom in deciding how to teach the national curriculum. So, two teachers handling two different classes (homerooms) in the same grade in the same school may have very different approaches. As there are no standardized exams, there is no way to really know if all the students in the same grade are at a comparable level at the end of the year. If your child gets a good teacher, lucky child, if the teacher is not good, oh well!
Coming to the students, while they have less pressure, the onus is more on them to evolve a method they can follow to study. They do get help from the teachers, but the system doesn't "push" them, so motivating oneself is very important. There is not much homework, and it is easy to think that what they learn in class is "enough". It often is in smaller grades, if they are attentive in class. But if they don't get used to studying at home, they will find it more and more difficult as they go to higher grades.
After 6th grade, they get separate teachers for subjects, and their grades also are awarded on more stringent criteria. So the level of work they needed to put in and the level of understanding of a topic they had to demonstrate to get grade X or Y in 6th grade is usually no longer enough to get similar grades. This is where the role the homeroom teacher played up until 6th grade in getting their basics right makes a real difference.
As the same teacher handles most of the subjects until 6th grade, it is also easy for the teacher to schedule any tests and homework so as not to put students under much pressure. This changes in 7th grade as each teacher will schedule tests and homework independently. So they suddenly start getting work from all directions. If they haven't developed a habit of studying at home, they will surely feel overwhelmed initially.
Another thing we often hear is how the system is not test-oriented, there is no competition, students compete with themselves etc. This is true to a great extent, and the grades are known to the student, teacher and parents alone and not to other students (of course, kids discuss grades among their friends). But, when there are limited seats there will always be tests and competition. The first time the students come up on true "competition" is when they have to go to the upper secondary schools (Lukio) after their 9th grade. The best schools have their own entrance tests and the students also need high GPA to get in. Even if the student is not aiming for the best Lukios, they are still ranked by their GPAs in other schools they apply to. So, of course, there is "pressure" on the students. It's just that it's not their teacher or school putting them under pressure on a daily basis to improve their grades. Students' grades from 8th grade onwards count towards their final GPA in 9th, so that's two years of pressure. But, Lukio education is mandatory in Finland. The system will provide a study place for the student somewhere. So I guess, we could also say that the students only need to put themselves under as much pressure as they want.
The 3 years of Lukio is a high pressure environment, especially something like IB. Their workload in Lukio is even higher than in their years prior, and the grading is even stricter. If, as I said above, the student has not created their own system or approach to study, they will struggle in Lukio.
Based on my experience, most of what we hear in India about the Finnish education system applies till 6th grade - with often a large dependency on the competence of one individual teacher. After that, just like anywhere else in the world, there is pressure and good results need as much work and effort as you need elsewhere.
What is different compared to India is that the pressure from the family and society is much less. In India there is always pressure to get a "good education", which will land you a "respectable job". In Finland, there is no shame if a student does not want to go to university, or if they choose a vocational training of their liking etc. I very much doubt if kids of Indian parents in Finland feel any less pressure in higher grades than they would do in India
Among my two kids the elder one was in English medium and younger one is in Finnish medium. There is a noticeable difference between the level of support students get in both systems. The Finnish medium provides more help to students and there are more tools/support available to students. The Finnish medium also has weighted curriculum system, where students from 3rd grade onwards can have more emphasis on various subjects like math, science, arts, music, sports, IT etc. So the kids have the opportunity to choose their own study paths from a young age. The admission to the weighted curriculum programs is based on entrance tests (in 3rd grade and 7th grade).
