What each paper covers

Topic weightings summarised from the CAPS examination guidelines so you can prioritise revision. Exact questions change each year - use this as a map, not a prediction.

Paper 1 - 150 marks (2½ hours)

Paper 1 mixes life processes at molecular and organism level - DNA, meiosis, reproduction, genetics and related human physiology strands depending on the year. Label diagrams fully and use scientific terms from CAPS rather than everyday wording.

  • DNA code, protein synthesis and meiosis40 marks
  • Reproduction in vertebrates / human reproduction35 marks
  • Genetics and inheritance40 marks
  • Responding to the environment (nervous / human eye as examined)35 marks

Paper 2 - 150 marks (2½ hours)

Paper 2 typically covers evolution, diversity, and plant/animal life-process themes that complement Paper 1. Expect data-response and experimental design style questions - state the variable, control and reliability factors when asked.

  • Evolution by natural selection and human evolution45 marks
  • Diversity of life / diversity of plants and animals as examined35 marks
  • Life processes supporting life (plants / photosynthesis / transport)40 marks
  • Environmental studies and human impact30 marks
