Topic-by-topic practice packs for Cambridge Lower Secondary Stage 7, 8 and 9. Biology, Chemistry and Physics.
A quick look at what's new before you pick a topic below. For the full picture across all three subjects, see the complete Stage 7–9 guide.
Biology, Chemistry and Physics each get their own space on the timetable, building the core vocabulary and classification skills everything later builds on.
Questions shift from naming and describing to reasoning through cause and effect — students now need to explain a process, not just label its parts.
Topics get noticeably harder across all three strands — think plant processes and carbon cycling, how fast reactions happen and why, and how heat and circuits actually behave.

Science boosters are single-topic Cambridge Lower Secondary practice packs covering Biology, Chemistry and Physics — each with a cheat sheet, 20 leveled questions and full worked solutions.
Cambridge Lower Secondary Science (syllabus code 0893) is assessed at Stage 9 through the Cambridge Lower Secondary Checkpoint examination, which reports separate scores for Biology, Chemistry and Physics rather than a single combined science grade. Each discipline receives a separate strand-level score on the 0 to 50 scale. Source: Cambridge Lower Secondary Science (0893) Syllabus, Cambridge Assessment International Education
