The Organization for Economic Co-operation and Development (OECD) released the results of its 2015 global rankings on student performance in mathematics, reading, and science, on the Program for International Student Assessment, or PISA.

The PISA is a worldwide exam administered every three years that measures 15-year-olds in 72 countries. About 540,000 students took the exam in 2015.

The US saw an 11-point drop in average score for math, while remaining relatively flat in reading and science.

Each testing year, the OECD releases some sample questions from the current year's exam. This year, it released science questions, and has archived math and reading questions on its site. Business Insider pulled questions from each section and included them below.

Take the four-question quiz below to get an idea of how you'd fare on the PISA exam.
