Shanghai top maths, science and reading tests

Eyebrows were raised when the results of the Organisation for Economic Co-operation and Development's international maths, science and reading tests - the Programme for International Student Assessment (Pisa) tests - were published.

Shanghai, taking part for the first time, came top in all three subjects.

Meanwhile, Hong Kong which was performing well in the last decade of British rule, has gone from good to great. In this global ranking, it came fourth in reading, second in maths and third in science.
