Greek pupils score below average on OECD's PISA tests
Greek teenagers scored below average marks in tests carried by the Organization for Economic Cooperation and Development (OECD).
Roughly 500,000 15-year-old pupils in 65 countries took the Program for International Student Assessment (PISA) tests and students from Greece missed the average of about 500 points in math, sciences and reading.
Literacy in math and reading were a few points down on the last PISA results in 2009.
Greece is only one of three EU countries, where the number of students with low results increased over the last four years.
