The flowchart below shows how to pick the right answer strategy on Paper 1 based on the marks and command word:

flowchart TD
    A[Read question, note marks] --> B{Marks in brackets?}
    B -->|1-2 marks| C[Short answer: 1 sentence per mark]
    B -->|3-4 marks| D{Includes 'calculate'?}
    B -->|6-8 marks| E[Extended response: plan + paragraphs]
    D -->|Yes| F[Show formula, working, units]
    D -->|No| G[Medium answer: 1 distinct point per mark]
    C --> H[Move to next question]
    F --> H
    G --> H
    E --> I[Plan 1-2 min, write 6-8 min, conclude]
    I --> H

Strategy for Short-Answer Questions (1-2 marks)

Short-answer questions test recall. They usually start with "State", "Name", "Give", or "Identify".

Strategy:

1. Read the question carefully
2. Give a direct, precise answer
3. Do not write more than needed — save time for longer questions
4. If the question asks for "two" reasons, give exactly two (not one, not three)

Example: "State the purpose of the MAR (Memory Address Register)." (1 mark)

Answer: The MAR holds the address of the memory location to be read from or written to.

OCR Exam Tip: For 1-mark questions, one clear sentence is sufficient. Do not write a paragraph — you cannot get more than 1 mark, so additional writing wastes time.

Strategy for Medium-Answer Questions (2-4 marks)

Medium questions require more detail. They often use "Describe" or "Explain".

Strategy:

1. Check the mark allocation — aim for one distinct point per mark
2. Use technical vocabulary
3. For "explain" questions, link cause to effect using "because" or "therefore"
4. Show your working for calculations

Example: "Explain two advantages of using a solid-state drive over a hard disk drive." (4 marks)

Answer:

• An SSD has no moving parts, so it is more durable and less likely to be damaged if the device is dropped (1 mark for point, 1 mark for explanation)
• An SSD can access data much faster because it uses electronic circuits rather than a physical read/write head, which reduces boot-up and loading times (1 mark for point, 1 mark for explanation)

Strategy for Calculation Questions (2-4 marks)

Calculation questions appear frequently in Paper 1, especially for file sizes and data units.

Strategy:

1. Write the formula first — this can earn a method mark
2. Substitute the values clearly
3. Show every step of your working
4. State the units in your final answer
5. Double-check by estimating whether your answer is reasonable

Example: "A digital image has a resolution of 1920 x 1080 pixels with 24-bit colour depth. Calculate the file size in megabytes." (3 marks)

$$\begin{aligned} \text{File size} &= \text{width} \times \text{height} \times \text{colour depth} && \text{(1 mark for formula)}\\ &= 1920 \times 1080 \times 24\\ &= 49{,}766{,}400 \text{ bits} && \text{(1 mark for calculation)}\\ &= 6{,}220{,}800 \text{ bytes} \quad (\div 8)\\ &= 5.93 \text{ MB} \quad (\div 1024 \div 1024) && \text{(1 mark for correct answer with units)} \end{aligned}$$File size​=width×height×colour depth=1920×1080×24=49,766,400 bits=6,220,800 bytes(÷8)=5.93 MB(÷1024÷1024)​​(1 mark for formula)(1 mark for calculation)(1 mark for correct answer with units)​

OCR Exam Tip: Even if you get the final answer wrong, you can still earn marks for writing the correct formula and showing your working. Never leave a calculation question blank.

Strategy for Extended Response Questions (6-8 marks)

Extended response questions are the most challenging. They require a well-structured, detailed answer that demonstrates deep understanding.

Strategy:

1. Read the question twice — underline key words and the command word
2. Plan your answer — spend 1-2 minutes jotting down key points in rough
3. Structure your answer with clear paragraphs:
   • Introduction (optional, 1 sentence)
   • Main points (2-3 paragraphs)
   • Conclusion (if discussing/evaluating)
4. Use technical terminology correctly
5. Address all parts of the question
6. Write legibly — examiners cannot mark what they cannot read

Common extended response topics in Paper 1:

• Compare cloud storage vs local storage
• Discuss ethical implications of data collection
• Evaluate network topologies for a given scenario
• Explain how the CPU executes instructions
• Discuss the environmental impact of technology

Worked Extended Response Example

Question: "Discuss the advantages and disadvantages of using cloud storage for a small business." (6 marks)

Plan (in rough):

• Advantages: access anywhere, scalability, automatic backups
• Disadvantages: internet dependency, ongoing costs, security concerns
• Conclusion: suitable if internet is reliable

Answer:

Cloud storage offers several advantages for a small business. Files can be accessed from any device with an internet connection, which supports remote working and collaboration between employees in different locations. Cloud storage is also scalable, meaning the business can increase or decrease storage as needed without purchasing new hardware. Additionally, cloud providers typically offer automatic backups, reducing the risk of data loss.

However, there are disadvantages. Cloud storage requires a reliable internet connection; if the connection is lost, employees cannot access their files. There are also ongoing subscription costs, which may be more expensive over time than purchasing a one-off local storage solution. Furthermore, storing sensitive business data on third-party servers raises security and privacy concerns, as the business must trust the cloud provider to protect their data.

Overall, cloud storage is likely a good choice for a small business that has a reliable internet connection and values flexibility, but the business should ensure it chooses a reputable provider with strong security measures and should maintain local backups of critical data.
