LGCSE Biology (0180) case studies
LGCSE Biology (0180) · Put your knowledge to work in context.
LGCSE Biology (0180) is a secondary-level biology qualification for learners who want a single, coherent introduction to living systems before moving on to A-level biology, vocational health or environmental courses, or employment. It suits school candidates studying alongside other subjects and independent or home-educated learners who need a recognised biology credential with a practical component. The syllabus is organised into eight domains: cells and cell processes; organisation and maintenance of the organism; genetics and inheritance; ecology and the environment; reproduction and development; coordination and response; evolution and adaptation; and experimental skills and scientific enquiry. Assessment mixes multiple-choice, structured short-answer and extended free-response questions with a practical or experimental skills element, so you are tested on recall, data interpretation, experimental design and extended writing. The LGCSE Biology (0180) case studies are 5 cases and about 2,686 words.
