How do you tackle the dreaded 12-mark extended evaluation questions? Read our exam strategy below.
The secret to 12-mark evaluation questions
Every Unit 1 exam paper ends with one or two extended 12-mark evaluative scenario questions (e.g. "Evaluate the implications for a retail business of migrating its customer databases entirely to a public cloud service").
The Distinction 4-step answer formula
- Technical advantages (with commercial context): Don't just say "cloud is scalable." Explain that automated horizontal scaling prevents website crashes during seasonal promotional surges (e.g. Black Friday), protecting revenue.
- Technical risks and limitations: Discuss data sovereignty under UK GDPR, vendor lock-in risks, ongoing subscription operational expenditure (OpEx), and dependency on third-party SLA uptime.
- Counter-measures and mitigation: Propose hybrid cloud deployment or multi-region redundancy to mitigate server downtime.
- Supported final judgement: Make a definitive recommendation explicitly tailored to the scenario's budget and technical staff capabilities.
Core legislation you must memorize
Examiners routinely ask 4-to-6 mark questions testing statutory compliance. Know these four acts inside out:
- Data Protection Act 2018 / UK GDPR: The seven key principles (lawfulness, purpose limitation, data minimisation, accuracy, storage limitation, integrity/confidentiality, accountability).
- Computer Misuse Act 1990: The three specific offences (unauthorised access; unauthorized access with intent to commit a crime; unauthorized modification of computer materials).
- Copyright, Designs and Patents Act 1988: Intellectual property protection for software code and digital assets.
- Health and Safety at Work Act 1974 (Display Screen Regulations): Ergonomics, RSI, and visual display compliance.
