Tips
GAC Science is two modules and they do different jobs. GAC013 is about science itself, its history, the scientific method, the language of units and notation, how the discipline is organised and the issues it raises. GAC023 is combined subject content, covering biology and classification, ecosystems, earth resources, chemistry and its environmental effects, and wave motion in physics.
The investigation is the centrepiece. Planning and carrying out an experiment, then writing it up to scientific and academic conventions, appears as an outcome in both modules and carries substantial weight.
Units and notation are assessed explicitly. Writing a quantity with the right symbol, the right unit and a sensible number of significant figures is a named outcome, not a presentation detail.
The breadth is deliberate. GAC023 crosses biology, chemistry, earth science and physics in one semester, so the aim is confident general science in English rather than specialist depth in one subject.
Practice on this site is original, and the science content borrows explanations and diagrams from our IGCSE and A-Level material where the topic is genuinely the same.
