The Lower Sixth Competition

This competition aims to stretch and challenge students interested in chemistry, and will provide an excellent experience for anyone considering taking their studies further. Set by an experienced team of teachers and university chemists, it is designed to be accessible to Year 12 students but will take them significantly beyond the syllabus and encourage them to think about science in the way they would at university. Past papers will provide a valuable resource for teachers. This competition is open to students studying in the UK in Year 12 (Lower 6th) or below. It will take the form of a 90 minute written paper which students will take at school. Students who do well in the competition will be sent certificates of achievement, and those who perform best will win an invitation to a residential camp at the University of Cambridge at the end of August.
