Mark Scheme Patterns & Essay Technique

Understanding how AQA marks your answers is one of the most powerful revision strategies you can use. The mark scheme is not a secret — it follows predictable patterns. If you know what the examiner is looking for, you can structure your answers to hit every mark point. This lesson dissects the mark scheme patterns for every question type and gives you proven techniques for maximising your marks.

How AQA Marks 9-Mark Questions: Levels of Response

The 9-mark extended response is the highest-value question on Papers 1 and 2 and also appears on Paper 3. It is marked using a levels-based mark scheme, which means the examiner reads your whole answer and decides which level it best fits.

The Three Levels

Level	Marks	What the Examiner Is Looking For
Level 1	1–3 marks	Basic. Isolated points of knowledge. Limited or no case study evidence. Simple statements without development. No connections between factors. Answer may be descriptive rather than analytical. May not address the command word properly.
Level 2	4–6 marks	Clear. Some developed points with some case study evidence. Some connections made between factors. Some analytical or evaluative comment. Answer addresses the command word but may lack consistency or balance.
Level 3	7–9 marks	Detailed. Thorough and accurate knowledge throughout. Well-developed chains of reasoning. Specific and accurate case study evidence (named places, dates, statistics). Clear connections between different factors. Balanced argument with a supported and justified conclusion. Consistent use of the command word.

What Moves You Between Levels

The key differences between levels are:

Level 1 → Level 2:

• You start developing your points instead of just stating them
• You include some case study evidence
• You begin to make connections between factors
• You use the command word (e.g. you actually evaluate if the question says "evaluate")

Level 2 → Level 3:

• Your case study evidence is specific — named places, dates, statistics (not vague references)
• You make clear connections between multiple factors
• Your argument is balanced — you consider different perspectives
• Your conclusion is justified — you explain WHY you reached that conclusion, not just what it is
• Your chains of reasoning are fully developed — each point has a clear cause-effect structure

Exam Tip: The single biggest difference between Level 2 and Level 3 is the quality of case study evidence. "A city in Brazil" is Level 1. "Rio de Janeiro" is Level 2. "Rio de Janeiro, where the Favela Bairro project invested $300 million to improve 253 favelas between 1995 and 2008" is Level 3.

6-Mark "Explain" Questions

6-mark explain questions are extremely common across Papers 1 and 2. They require you to give two or three developed points with specific case study evidence.

Structure for a 6-Mark Answer

Write two or three PEEL paragraphs:

• Point — make a clear geographical point
• Evidence — support it with case study evidence (named place, date, statistic)
• Explanation — explain the process or reason in detail
• Link — link back to the question or to the next point

Example: "Explain the challenges caused by rapid urbanisation in LICs." (6 marks)

Point 1: One major challenge is the growth of squatter settlements. Evidence: In Lagos, Nigeria, over 60% of the population lives in informal settlements such as Makoko, a floating slum built on stilts over Lagos Lagoon. Explanation: Rapid rural-to-urban migration overwhelms the city's ability to provide formal housing, so migrants build makeshift homes on any available land, often in hazardous locations. Link: This creates further challenges including poor sanitation, disease, and fire risk.

Point 2: Another challenge is inadequate infrastructure, particularly water supply and sewage. Evidence: In Lagos, only about 10% of the city is connected to the sewerage system, and many residents rely on shared wells or water vendors who charge high prices. Explanation: The city's infrastructure was designed for a much smaller population and has not been expanded fast enough to keep pace with growth. Link: This means waterborne diseases such as cholera and typhoid are common, especially in informal settlements.

Exam Tip: Two well-developed points with strong evidence will score higher than three or four undeveloped bullet points. Quality beats quantity on 6-mark questions.

Case Study Requirements: Named, Located, Detailed

AQA expects case studies that are NAMED, LOCATED, and DETAILED. Vague case studies are one of the most common reasons students score in Level 1 or Level 2 instead of Level 3.

What Counts as Good Case Study Evidence?

Quality Level	Example	Likely Mark Level
Vague	"A tropical storm caused lots of damage in Asia."	Level 1 (1–3)
Named	"Typhoon Haiyan hit the Philippines in 2013."	Level 2 (4–6)
Named + Located + Detailed	"Typhoon Haiyan struck the Philippines on 8 November 2013 with wind speeds of 315 km/h, killing over 6,300 people and displacing 4 million. The city of Tacloban was almost completely destroyed by a storm surge reaching 5 metres."	Level 3 (7–9)

What You Need for Each Case Study

For every case study you have learned, make sure you know:

Element	Why It Matters
Name	Names the event, project, place, or policy
Location	Where exactly — country, region, city, grid reference if relevant
Date	When it happened — year at minimum, specific date for major events
Key statistics	Numbers that demonstrate scale, impact, or change (deaths, costs, measurements, percentages)
Causes	What caused the event or situation — both physical and human factors
Effects	Social, economic, and environmental impacts — both short-term and long-term
Responses	What was done about it — immediate responses and long-term management
Evaluation	Was the response effective? What could be improved? Who benefited and who didn't?

Exam Tip: Create a case study fact file for each required case study. Include 5–8 key statistics you can use in the exam. Statistics make your answers specific and credible.

The Difference Between "Assess" and "Evaluate"

Students frequently confuse these two command words. While they overlap, they require subtly different approaches.

Assess

"Assess" means weigh up the importance, significance, or effectiveness of something. You are making a judgement about how significant or successful something is.

Structure:

1. Identify the factors or strategies being assessed
2. For each one, explain its importance/significance/effectiveness
3. Compare the relative importance of different factors
4. Conclude with a judgement: which is the MOST important/significant/effective, and why?

Example question: "Assess the importance of plate tectonics in causing natural hazards." (9 marks)

What the examiner wants: Discuss plate tectonics as a cause of natural hazards, but also consider other factors (climate, weather, human activity). Conclude by judging HOW important plate tectonics is relative to other factors.

Evaluate

"Evaluate" means consider the advantages and disadvantages (or strengths and weaknesses) and reach a supported conclusion about overall success or value.

Structure:

1. Identify advantages/strengths
2. Identify disadvantages/weaknesses
3. Weigh these against each other
4. Conclude with a supported judgement: is it overall positive or negative, successful or unsuccessful?

Example question: "Evaluate the effectiveness of hard engineering strategies for coastal management." (9 marks)

What the examiner wants: Discuss specific hard engineering strategies (sea walls, groynes, rock armour, gabions), give advantages and disadvantages of each, use case study evidence, and conclude by judging whether hard engineering is overall effective or not.

Key Difference

• Assess = How important/significant is it? (relative to other factors)
• Evaluate = How successful/effective is it? (advantages vs disadvantages)
