Whilst Chemistry is a universal science, studying it at IB is quite different from other courses. The most distinctive difference is that it has considerably more breadth in the coverage of topics. The 11 topic core include: Quantitative Chemistry, Atomic Structure, Periodicity, Bonding, Energetics, Kinetics and Organic Chemistry.

The seven optional topics include modern analytical chemistry, human biochemistry, medicines and drugs, food chemistry, chemistry in industry and society, further organic chemistry and environmental chemistry. You'll be expected to become adept at practical laboratory work, data collection and manipulation, and build a strong scientific awareness. External assessment consists of three written papers, which you may find easier to face having accessed the Marked by Teachers collection of IB Chemistry essays. Internal assessment, which makes up 24% of the marks, consists of an interdisciplinary project, a variety of short and long-term practical investigations and some subject-specific projects.
