Try OECD's International PISA Math Quiz 2012

12/4/2013

The Organization of Economic Cooperation and Development (OECD) has a PISA program which examines and compares the performance of worldwide students, schools and education systems on a three-year basis. In the PISA tests, 15-year-old students from different countries take math, reading, and science tests. In 2012, around 65 countries and economies took part in PISA, and the rankings of student competence of these countries have been revealed recently.

 

OECD has posted some sample questions of the 2012 PISA math quiz on its official website, which were soon forwarded by some major media in the western world. The questions cover the areas of algebra, graph, comparison, etc. The media call their adult readers to try these questions to see if they can get all correct, and the result is somewhat frustrating. Here Acadsoc also encourages our readers to have a go! (Hint: Some of the questions below are tricky indeed.)
