Relaxed vs strict: Which type of education is best?

28 November 2012 Last updated at 01:19 GMT

Finland and South Korea have topped an international league table of education systems - despite taking very different approaches to learning.

Finnish schools emphasise trust and students there do the fewest hours in class per week of the developed world. By contrast, South Korean children can spend 12 hours a day studying.

The rankings combine international test results and data such as graduation rates between 2006 and 2010.
