Think you're smarter than a 15-year-old? Try some PISA test questions and find out

The Programme for International Student Assessment (PISA), developed by the Organisation for Economic Co-operation and Development (OECD), evaluates the skills of 15-year-olds in areas such as reading, mathematics, and sciences every three years. The article invites readers to test their knowledge through some of the questions in these international tests. The goal is to allow adults to compare their performance with that of a 15-year-old, checking if they are smarter than these students. This type of assessment is used internationally to measure the quality of education in different countries.
