Biology
OCR Paper 2
Paper 2 (J247/02 Foundation and J247/04 Higher) of the OCR GCSE Biology A (Gateway Science) course: a 1 hour 45 minute written exam of 90 marks (50% of the qualification) on topic B4 community level systems, topic B5 genes, inheritance and selection and topic B6 global challenges, with the practical skills of topic B7. The same topics are in the Biology papers of OCR Combined Science A, so a lesson only the separate Biology course teaches is tagged Separate only, and a lesson only the Higher tier sets is tagged Higher.
