Finnish students stay in college longer than in any other developed country save Austria, the Netherlands and Denmark, getting their first university degree on average at 29, according to a 2013 report by the Organization for Economic Cooperation and Development. That compares with 24 years for Britons, 26 for Germans and the OECD average of 27 years. Most Finns who graduate from college get a master’s degree.
There is more here. Of course that undoes a lot of the benefits from their excellent primary education system.
