Welcome to the website of C3L6, the Cambridge Chemistry Challenge!
We have made some changes to the website, and if you have reached this page as a student, you may be most interested in viewing past papers on the Downloads page. This does not require you to log in.
While the official registration is now closed, as a teacher you can still register your school/college, but please make sure to also email "email@example.com" so that we will know to send you the paper. The competition window will open on June 8th and run until June 25th, when the markscheme will be published. You will then have until June 30th to enter the marks. We are hoping to moderate the highest-scoring scripts and to invite the Roentgenium winners to one of the courses to be held in Cambridge in late August/early September.
