Yes, indeed. Also comparison with a number of countries, instead of just Finland, can give you a better idea of what works and what is just an accidental feature.

For example, in Germany pupils who fail two (or so) classes, have to repeat the entire year. That ends up costing the economy way more than giving those weak students special attention, and extra teacher time, to get them up to speed again. Also the German school system segregates people into university-bound and not university-bound at age ten. Switching between tracks later is possible, but hard.
