27. FINAL PAPER 2 COMMON TRAPS

Trap: Ignoring command word

• “Describe” means what you see.
• “Explain” means why/how.
• “Suggest” means sensible applied idea.
• “Compare” means both sides.
• “Evaluate” means strengths + weaknesses + judgement.

---

Trap: Ignoring the context page

• The opening country/island facts are clues.
• Use:
  • climate
  • terrain
  • economy
  • population
  • resources
  • hazards
  • map location
• Generic answers lose easy application marks.
• Context makes answers stronger.

---

Trap: Missing units

• Use:
  • people/km²
  • %
  • °C
  • tonnes
  • km
  • kg/ha
  • ppm
• Units matter especially in calculations.
• Mark schemes stress using appropriate units.

---

Trap: Wrong percentage denominator

• Percentage increase uses original value.
• Formula:
  • increase ÷ original × 100
• Not:
  • increase ÷ new × 100
• Show working.
• Round only at the end.

---

Trap: Vague environmental answers

• Weak:
  • “It affects nature.”
• Strong:
  • “It destroys habitats, so species lose food and shelter and biodiversity decreases.”

---

Trap: Repetition

• Weak:
  • “Creates jobs.”
  • “Gives employment.”
  • “People get work.”
• Strong:
  • “Creates jobs.”
  • “Increases local income.”
  • “Improves infrastructure.”

---

Trap: Contradiction

• Do not write both:
  • “Fish increase”
  • “Fish decrease”
• Unless comparing different times or species.
• Contradictions can block marks.
• Keep answer controlled.

---

Trap: Too many answers in list questions

• If asked for two, give your best two first.
• Do not throw random weak points before strong ones.
• List rule can punish messy ordering.
• Quality beats chaos.
• Marks are not collected by panic-writing.

---

Trap: Not separating advantages and disadvantages

• Use headings:
  • Advantages
  • Disadvantages
• Makes examiner’s life easy.
• Easy examiner life = fewer silly lost marks.
• Old-school but undefeated.

---

Trap: Economic vs environmental confusion

• Economic:
  • jobs
  • income
  • trade
  • taxes
  • costs
• Environmental:
  • pollution
  • habitat loss
  • biodiversity
  • erosion
  • water quality
• Social:
  • health
  • education
  • housing
  • quality of life
  • migration

• Underline:
  • climate
  • terrain
  • population
  • economy
  • resources
  • hazards
  • map location

---

Step 2: Read the command word

• State = direct answer

• Explain = chain
• Suggest = applied idea
• Compare = both sides
• Evaluate = balanced judgement

---

Step 3: Match marks to points

• 1 mark = 1 point
• 2 marks = 2 points or 1 developed point
• 3 marks = 3-step chain
• 4 marks = 4 points or 2 developed chains
• 5–6 marks = several developed points + judgement if needed

---

Step 4: Use case-study clues

• Hot climate?
  • drought, irrigation, tourism, wildfires
• Coast?
  • fishing, ports, tourism, sea level rise
• Mountains?
  • transport difficulty, landslides, tourism
• Mining economy?
  • jobs, exports, pollution, habitat loss
• Tourism economy?

---

Step 5: Check before moving on
