Ideas, worked examples, then practice
Each topic opens with what you should be able to do. Illustrated panels keep equations, structures and diagrams beside the explanation. “How IB asks this” shows how the topic is examined, so you know what to practise.
Basic and Tutorial practice build your working and Advanced practice stretches it. Tools and inquiry covers measurement, uncertainty, graphs and the skills of an investigation, and a closing section shows how to make your chemistry assessable. HL-only material is marked throughout.
Full worked solutions are free at ibtuition.sg/guidebook/chemistry/, including the printed QR links.
