We use the Cuttle online competition hosting system used by both Bebras UK and OUCC. This is part of our progression to closer integration within the UKCT Challenges national framework.

Questions appear online as part of the website so no additional printed paper is required. Solutions are provided below to all but the most recent of each round; teachers can contact us directly for a link to the most recent solutions if useful.



The 2021-22 questions will become available for practice without login once each round has completed. Public example solutions will be retained off of this site for a year although teachers may email the competition organiser to request them and pass them onto students if helpful.
