Paper 1 Strategies: Short-Answer, Medium-Answer and Extended-Response Questions

AQA GCSE D&T Paper 1 (Core Technical Principles) is worth 100 marks and lasts 2 hours. This lesson provides targeted strategies for each question type you will encounter, with worked examples. Specification reference: AQA 8552, all of Sections 3.1 and 3.2.

Time Management

Question Type	Typical Marks	Recommended Time
Multiple choice / 1-mark	1 mark	30–45 seconds
Short answer	2 marks	1.5–2 minutes
Medium answer	3–6 marks	4–7 minutes
Extended response	8–12 marks	10–15 minutes
Total	100 marks	120 minutes

Key rule: 1.2 minutes per mark. If you spend 10 minutes on a 2-mark question, you are stealing time from higher-value questions.

AQA Exam Tip: Start by scanning the whole paper. Answer the questions you find easiest first to build confidence and secure marks. Return to harder questions afterwards.

Strategy 1: Short-Answer Questions (1–2 marks)

What to Expect

• "State one advantage of..." (1 mark)
• "Name the process used to..." (1 mark)
• "Give two reasons why..." (2 marks)
• "What is meant by the term...?" (1 mark)

How to Answer

• Be concise. Write one clear sentence per mark.
• Do not explain unless the question asks you to.
• Use correct technical vocabulary — "injection moulding" not "squirting plastic into a shape."

Worked Example (2 marks)

Question: Give two advantages of using MDF instead of natural timber for making a set of kitchen shelves.

Answer:

1. MDF has no grain direction, so it does not warp or split, giving a more stable shelf. (1)
2. MDF has a smooth, consistent surface that can be easily painted or laminated without grain showing through. (1)

Strategy 2: Medium-Answer Questions (3–6 marks)

What to Expect

• "Describe how..." (3–4 marks)
• "Explain why..." (3–4 marks)
• "Compare..." (4 marks)

How to Answer

• Match your points to the marks. A 4-mark question needs 4 distinct points.
• Use the PEE structure for explain questions: Point → Evidence/Example → Explanation.
• Use numbered steps for describe questions (especially process descriptions).
• Use a table for compare questions to ensure you cover both items.

Worked Example: Describe (4 marks)

Question: Describe the process of sand casting an aluminium bracket.

Answer:

1. A pattern of the bracket (made slightly oversize to allow for shrinkage) is placed in a two-part mould box (cope and drag) and packed with moulding sand (greensand). (1)
2. The pattern is removed, leaving a cavity in the shape of the bracket. A runner (channel for pouring) and riser (air escape hole) are formed. (1)
3. Molten aluminium (approximately 660 °C) is poured into the runner and fills the cavity. (1)
4. The metal is allowed to cool and solidify. The mould is broken open, and the casting is removed, cleaned (fettled) and machined to the final dimensions. (1)

Worked Example: Explain (3 marks)

Question: Explain why stainless steel is used for kitchen sinks.

Answer:

• Stainless steel is highly resistant to corrosion because it contains chromium (minimum 10.5%), which forms a protective oxide layer on the surface. This is essential for a product in constant contact with water. (1)
• It is easy to clean and hygienic — the smooth surface does not harbour bacteria, making it suitable for food preparation areas. (1)
• It is strong and durable — it can withstand heavy use (heavy pans, boiling water) without denting, cracking or staining over many years. (1)

AQA Exam Tip: For "explain" questions, every point should contain a reason. Look for the word "because" in your answer — if it is not there, you are probably describing, not explaining.

Strategy 3: Extended-Response Questions (8–12 marks)

What to Expect

Extended-response questions are the highest-value questions on Paper 1. They require:

• A structured argument (introduction, main points, conclusion).
• Detailed knowledge with specific examples, data and technical vocabulary.
• Application to the given context or scenario.
• Often use command words like "evaluate," "discuss" or "compare and justify."

The PEEL Structure for Extended Responses

Step	What to Do	Example
P — Point	State your main argument or factor	"One key advantage of injection moulding for this product is..."
E — Evidence	Provide specific technical detail or data	"...the cycle time is only 15–30 seconds per unit, meaning 10,000 units can be produced in..."
E — Explain	Link the evidence to the question context	"...this makes it the most cost-effective method at the required production volume of..."
L — Link	Connect back to the question or lead to the next point	"However, the high initial tooling cost means this is only viable if..."

Worked Example (8 marks)

Question: A manufacturer produces stainless steel water bottles in batches of 5,000. Evaluate the use of deep drawing as the manufacturing process. Consider alternative processes and recommend the most suitable method. (8 marks)

Model Answer:

Deep drawing involves placing a flat sheet (blank) of stainless steel over a die and using a punch to push it into the die cavity, forming a hollow cylindrical shape. This is done on a hydraulic press.

Advantages of deep drawing for this application:

• Produces a seamless bottle body with no welded joints — this is essential for a water bottle that must be leak-proof and hygienic. (1)
• Very fast once set up — cycle time is seconds per bottle, making it efficient for a batch of 5,000. (1)
• Produces a consistent wall thickness and smooth internal surface, important for food-safe products. (1)

Disadvantages:

• High tooling cost — the punch and die are expensive to manufacture from hardened tool steel. For 5,000 units, this cost must be carefully calculated to ensure viability. (1)
• Limited to simple cylindrical or tapered shapes — complex geometries (e.g. bottles with handles or unusual profiles) cannot be deep drawn. (1)

Alternative process — spinning: Metal spinning uses a rotating mandrel and a forming tool to shape a flat disc of metal into a hollow form on a lathe. It has lower tooling costs than deep drawing but is slower (1–2 minutes per bottle) and produces less consistent wall thickness. (1)

Recommendation: For a batch of 5,000 identical stainless steel water bottles, deep drawing is the most suitable process. The seamless construction ensures leak-proof performance, the fast cycle time keeps per-unit costs low, and the tooling investment is justified at this volume. Spinning would be more suitable for smaller batches (under 500) where tooling costs cannot be recovered. (2)

AQA Exam Tip: Extended responses should be 200–350 words. Use paragraphs and technical vocabulary. Always finish with a clear conclusion that directly answers the question.

General Paper 1 Tips

Tip	Reason
Read the whole paper first	Identify easy marks and plan your time
Underline command words and key terms	Ensures you answer the right type of question
Show your working in calculations	Partial marks are awarded for correct method even with a wrong final answer
Use diagrams where helpful	A labelled diagram can earn marks and save writing time
Do not leave blanks	Always attempt every question — even a partial answer may earn marks
Check your answers	If you finish early, re-read your extended responses for clarity and completeness
Write in full sentences for 3+ mark questions	Bullet points are fine for 1–2 mark questions, but examiners expect full sentences for longer answers
