There is sometimes a Christmas Quiz, sometimes not, with the most recent one being hosted in the 2017/18 school year. Although they are fun to take part in, if it goes ahead just depends if teachers are interested in spending a lunchtime trying to organise a bunch of (mostly) Year 8s and 9s and have the willpower to part with the chocolate prize at the end (often not).
Like most quizzes, it consists of guessing songs, movie titles, and dingbats.
