As well as covering all the chemistry content of the syllabus this site also covers all you need to cover the core of the IB, i.e. Theory of Knowledge (TOK), Creativity, Action & Service (CAS), and Extended Essay (EE). Also Included in this section, although not technically in the core, are the Learner Profile and the Nature of Science. Below are links to the pages on the site for first assessment in 2025.
