What is in GCSE OCR gateway biology?

what are the modules b1 b2 and b3 called? briefly, what is in each of them?

B1: Understanding Ourselves- Digestive system, essential nutrients blood pressure, homeostasis, drugs, genes and chromosomes, neurones, the eye, pathogens and immunity, hormones, respiration
B2: Understanding Our Environment- Classification, species, adaptation, photosynthesis, glucose and respiration in plants, global warming, endangered species, relationships between organisms, fossils
B3: Living and Growing- Cells (animal and plant), protein synthesis in DNA, closer look at enzymes, reproduction, growth (animals and plants), circulatory system, mitosis, meiosis, stem cells, selective breeding, genetic engineering, cloning, Dolly the Sheep , tropism, DNA fingerprinting

Possibly covers some more, but can’t remember off the top of my head. Check out BBC Bitesize http://www.bbc.co.uk/schools/gcsebitesize/ it’s pretty helpful, also most of my class like the CGP revision book, which covers the 6 modules. Hope that helped.
