Before you start

  1. This paper. This paper has three parts, and your admission year and mode decide which you sit: Part A only, 30 marks in 1 hour; Parts A and B, 50 marks in 1 hour 45 minutes; Parts A, B and C, 70 marks in 2 hours 30 minutes. The cover of your own paper says which applies to you.
  2. Most asked here. Scope of environmental studies and basic terms (16 papers), Solid waste management (15 papers), Water resources: use, conflicts, conservation (11 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.
