The Cambridge Chemistry Challenge (C3L6) is a global challenge for high school students co-sponsored by the Department of Chemistry and St Catharine's College at the University of Cambridge. It is officially recommended by the University of Cambridge as a high school academic program. C3L6 is a highly valued chemistry challenge for UK high schools, with over 10,000 students participating each year, and is often used as a pre-test for the UKChO (UK Chemistry Olympiad). It is aimed at high school students up to Year 11 and designed to extend chemistry knowledge in a challenging but fun way.
C3L6 is based on A-level chemistry knowledge, but is more difficult than A-level and examines students' ability to apply their A-level chemistry knowledge in a flexible way. It is a highly rewarding challenge for students who want to explore the eld of Chemistry further and its results are highly sought after by the world's leading universities. In the UK, the C3L6 invites no more than 60 top students each year to a residential camp at the University of Cambridge. Designed and taught by Cambridge professors, the camp aims to enhance the academic ability of young elites in Chemistry and to encourage and help outstanding students to understand and choose to study at Cambridge in the future.

The St Catharine's College, Cambridge Chemistry Camp is an annual chemistry camp organized for top students in the UK who have received the C3L6 Roentgenium Award, representing approximately the top 0.7% of C3L6 achievers. The camp is led by the renowned chemistry professor, Prof. Peter Woother, who serves as the head coach of the mentoring team. Due to the rigorous selection criteria and high academic standards, most outstanding students who participate are admitted to G5 universities such as Cambridge, Oxford, and Imperial College London in relevant majors.

Starting from 2024, St Catharine's College, University of Cambridge, in collaboration with ASEEDER, will selectively invite 35 students from China to participate in St Catharine's College, Cambridge Chemistry Camp. The camp aims to provide an in-depth exploration of chemistry and an opportunity to learn about the university-level chemistry courses at Cambridge.
Selected participants will engage in discussions on cutting-edge theories, conduct hands-on experiments to verify problem-solving approaches and receive an official certificate from St Catharine's College. Participants will also stay in dormitories at St Catharine's College and experience the traditional formal gown dinner of the University of Cambridge.

The Cambridge Chemistry Challenge Camp (C3L6 China Camp) aims to provide an opportunity for outstanding students who performed well in C3L6 to explore chemistry in-depth. Led by a team of professors from the C3L6, the camp brings international top-level chemistry classes to students in China, allowing them to interact and exchange ideas with chemistry elites from various schools across the country.
