Before you start

  1. This paper. Regular students sit Parts A and B, 50 marks in 1 hour 45 minutes. SOL students sit Parts A, B and C, 70 marks in 2 hours 30 minutes. The copy we hold is missing two printed pages, so Q2 to Q5 are not listed.
  2. Most asked here. Scope of environmental studies and basic terms (16 papers), Solid waste management (15 papers), Types of ecosystems (10 papers). These come back almost every year, so learn them first. The asked N× note beside each part counts the DU papers that set its topic.
  3. Pace. Two minutes a mark: about 20 minutes for each 10-mark question, with nothing spare in 2.5 hours. Move on when the time is up.
  4. Keep score. Every part opens a worked answer checked against the books. Turn the key when you have revised it; the boxes at the top fill in, on this device.
