🎯 Common Question Types and How to Answer Them:
- Push-pull question (4 marks): Give 2 push + 2 pull factors with a brief explanation for each. Do not just list them — explain how they cause migration.
- Explain challenges (6 marks): Use the TRAFFIC framework. Pick 3 challenges, name a case study for each, use specific data (km/h speeds, population figures, waste tonnage). Link each challenge to an underlying cause.
- Evaluate solutions (8 marks): Compare at least one top-down and one bottom-up solution. Use Mumbai Metro vs BRAC or Dharavi vs ADB embankments. Reach a judgement — which works better, for whom, and in what context? That judgement is what earns Level 3.
- "Using a named example" questions: Always name the city in your first sentence. Then deploy statistics. Examiners mark you on whether your evidence is specific and accurate.
📝 Key Command Words to Know:
- Describe: State the pattern, no explanation needed
- Explain: Give reasons, use "because" and "therefore"
- Evaluate: Weigh up both sides and make a judgement
- To what extent: Same as evaluate — reach a conclusion
- Assess: Consider evidence and judge its importance
⚠️ Common Mistakes to Avoid:
- Vague case studies: "In a developing country, there is a slum" scores nothing. Name the city, name the settlement, give a statistic.
- Listing without explaining: Writing "Mumbai has traffic, pollution, and flooding" is a list, not an explanation. Explain WHY each problem exists.
- Ignoring the evaluate instruction: In 8-mark questions, students who only describe and explain without making a judgement are capped at Level 2. Always end with "Overall, I would argue..."
- Treating informal settlements as purely negative: Dharavi has a £1 billion economy. Recognising complexity earns higher marks.
- Confusing LIC, NEE, and HIC: Know which category your case study cities fall into. Dhaka = LIC (Bangladesh, GNI ~$2,800). Mumbai = NEE (India). Tokyo = HIC (Japan). It changes the nature of the challenges and available solutions.
- Forgetting climate change links: Megacity flooding (Dhaka, Mumbai) is worsened by climate change. This connects to other topics and earns marks in synoptic questions.
Quick Check: Evaluate the effectiveness of one top-down and one bottom-up strategy to manage urban challenges in LICs or NEEs. (Practice your Level 3 answer — aim for 3–4 sentences with named evidence and a judgement.)
Model answer: Mumbai Metro Line 3 is a top-down strategy that cost ₹33,000 crore and will carry 1.7 million passengers per day, significantly reducing congestion on a city where average speeds are just 10 km/h. However, it took over 15 years to build and fares may exclude the 55% of Mumbai's population living in informal settlements — the people who arguably need transport most. In contrast, BRAC in Dhaka is a bottom-up NGO approach that has reached 100 million people through microfinance, health clinics, and schools in bastis, at a fraction of the cost. Its flexibility means it can respond to community needs faster than government infrastructure. Overall, both approaches are needed: top-down for large-scale infrastructure that only government can fund; bottom-up for reaching the communities that infrastructure misses. The most effective interventions — like Rio's Favela-Bairro scheme — combine both by using government funding to upgrade communities rather than replace them.
