Description

This document is designed for GCSE Combined Science: Trilogy Foundation Tier students preparing for the 2026 AQA examination series, including Year 11 candidates targeting grade 4–5 passes, resit students improving previous GCSE Biology results, and home-educated learners following the AQA 8464 specification. It is especially valuable for students learning how AQA awards marks in Foundation Tier Biology calculations, ecology fieldwork, genetics diagrams, practical investigations, and six-mark extended responses.

It is also essential for biology teachers, science departments, private tutors, revision-course providers, and parents supporting GCSE revision at home. The mark scheme can be used for timed mock marking, examiner-standard feedback sessions, intervention planning, standardisation exercises, and identifying common misconceptions in GCSE Biology assessments using authentic June 2025 examiner criteria.

⬤How AQA awards marks for homeostasis and diabetes questions involving insulin, blood glucose concentration, glycogen storage, pancreas function, and lifestyle management — plus common student errors flagged in the June 2025 series such as confusing glucose and glycogen — so you can pre-empt them before the 2026 exam.

⬤Examiner-approved methods for ecology required practicals including quadrat sampling, percentage-cover calculations, mean calculations, transects, and identifying abiotic and biotic factors affecting plant distribution — plus common student errors flagged in the June 2025 series involving incorrect percentage-cover working — so you can pre-empt them before the 2026 exam.

⬤The exact accepted answers for farming, biodiversity, peat compost, decomposition, carbon cycling, and greenhouse-gas explanations including accepted terminology for global warming and carbon dioxide release — plus common student errors flagged in the June 2025 series involving vague climate-change explanations — so you can pre-empt them before the 2026 exam.

⬤Mark-scheme expectations on evolution, fossils, plesiosaurs, antibiotic resistance, extinction evidence, and fossil-record limitations including accepted comparative statements and timeline calculations — plus common student errors flagged in the June 2025 series involving fossil interpretation — so you can pre-empt them before the 2026 exam.

⬤Real examiner guidance on genetics and inheritance questions involving chromosomes, alleles, gametes, Punnett squares, probability calculations, sex determination, and meiosis — plus common student errors flagged in the June 2025 series involving incorrect genotype probabilities — so you can pre-empt them before the 2026 exam.

⬤How AQA assesses hormones and contraception questions using level-of-response marking criteria, including hormonal methods, progesterone, oestrogen, FSH inhibition, and contraception advantages — plus common student errors flagged in the June 2025 series involving confusion between hormonal and barrier methods — so you can pre-empt them before the 2026 exam.
