Clever Clevedon School students are performing in the top 78 out of 1113 teams nationally in a prestigious code-breaking, maths and science competition.
The high-achieving students are exploring code-breaking challenges during the annual Alan Turing Cryptography Competition and are aiming to be ranked even higher.
In the competition, students solve puzzles online using their mathematical skills, with each new chapter accompanied by a story.
The idea is for the students to study and solve the techniques for sending secure communication, and is heavily based on mathematical theory, algorithms and computer science.
Assistant Coordinator in Maths Deb Griffiths said: “Our students are doing amazingly and are cracking multiple codes regularly.
“These challenges demonstrate the high and wide ranging abilities of our students. We are hoping to finish in the top 50 in the UK.”
