Since 1904, the College has set an annual general knowledge test, known as the General Knowledge Paper (GKP). In the past pupils sat the test twice: once unseen on the day before the Christmas holidays, and again when they returned to school in the New Year, after spending the holiday researching the answers. The test is now voluntary. It is well known to be highly difficult, a common score for the unseen test is just two correct answers from the list (180 questions in 2018). The best scores are 40 to 50 for the unseen test and about 270 out of 360 for the second sitting. Traditionally, the best scorers were given a half day free from school, while anyone doing particularly badly was given a detention.
