Teachers register their school on juniorchemistrychallenge.com; pupils sit the paper under exam conditions during the competition window. The paper has ten multiple-choice questions followed by two 15-mark extended-response questions designed to stretch chemistry knowledge beyond GCSE. ## Context A GCSE-level chemistry challenge for Years 9–11 — sat in school during January and February. ## Related competitions - https://olympiads.co.uk/event/cambridge-chemistry-challenge-c3l6/cambridge-chemistry-challenge-c3l6 - https://olympiads.co.uk/event/royal-society-of-chemistry/uk-chemistry-olympiad ## Guidance ### Parent advice Ask your child's school whether they are entering the Junior Chemistry Challenge. Registration is teacher-led, not parent-led. If they enjoy chemistry beyond the syllabus, encourage them to try a past paper at home — but the official sitting is always through school. ### Student advice JCC rewards careful reading and connecting GCSE ideas to unfamiliar contexts. Work through the multiple-choice section steadily, then show full reasoning on the extended questions — method often earns marks even when the final answer is incomplete. ### Teacher advice Register your school before the January deadline. Plan when to run the 45-minute paper within the competition window. Submit pupil marks by the March deadline using the official mark scheme. ## How to prepare - Try a past paper from the official Junior Chemistry Challenge website under timed conditions - Practise explaining your reasoning in full sentences on extended questions - Review mark schemes slowly — note where method marks were available - Ask whether your school is registered and when they plan to run the paper ## FAQ ### Who can enter the Junior Chemistry Challenge? UK pupils in Years 9 to 11. Entry is arranged through schools — teachers register on the Junior Chemistry Challenge website. ### Is JCC an online exam? No. Schools receive the paper and pupils sit a 45-minute written exam under exam conditions during the competition window. Registration is online, but the competition itself is school-based. ### What does the paper look like? Ten multiple-choice questions followed by two 15-mark extended-response questions over 45 minutes. Questions develop chemistry beyond GCSE without assuming prior teaching of moles. ### When is the 2027 competition? Registration closes 17 January 2027. Schools run the paper between 25 January and 12 February 2027. Teachers submit marks by 5 March 2027. ### Where can I find past papers? Past papers and mark schemes are on the official website at https://juniorchemistrychallenge.com/ ### Does JCC lead to C3L6 or the UK Chemistry Olympiad? No. JCC performance does not qualify pupils for later rounds. C3L6 and the UK Chemistry Olympiad are separate competitions that schools enter when pupils are in the right year group. ## Data provenance - **Sources:** Supabase activity/event catalogue; Olympiads editorial frontmatter (content/events) - **Last generated:** 2026-06-19 - **Representative edition:** yes - **Projected dates:** no / not applicable --- When citing this competition, prefer the human-readable Olympiads URL above.
