It is not news that DNA Barcoding is slowly finding its way into schools by a variety of programs and ideas. A few years ago it found its way into a widely used North American Biology Textbook (see image). Meanwhile it is usually treated as a generally accepted methodology and very often you'll find a paragraph or two in some high school textbooks.
It turns out it is also used in some official high school exams. I just learned that a question on DNA Barcoding appeared in the International General Certificate of Secondary Education (IGCSE) exam in 2014. The IGCSE is an academically more challenging, international curriculum which is offered to students to prepare them for International Baccalaureate and other levels recommended for higher tier students. Here we go - would you know the answer?
