Demonstrate understanding of a computer science concept
AS91898 is a 3-credit external exam (written under exam conditions) where you answer questions about a computer science concept — in recent exams this has included topics like artificial intelligence and encryption. You need to show you understand not just what the technology is, but how it works, why it matters, and what problems or challenges it raises.
You correctly identify the computer science concept, give accurate details about how it works or is used, and answer questions in the context asked (e.g. AI in healthcare, not just AI in general). You explain things like how data is processed or why a security risk exists — not just list physical features like 'cars have sensors'.
On top of the Achieved content, you explain the impact of the concept clearly — for example, explaining that faster AI diagnosis leads to better patient outcomes, not just saying 'AI is used in healthcare'. You understand the 'why' behind things, such as why older methods (like dip switches) were insecure compared to modern encryption, and you connect technical ideas to human effects like mental health or user behaviour.
You go beyond explaining to critically evaluating — for example, discussing the real limitations of SHA-256 or neural networks, not just describing them. You tackle future-proofing questions with genuine insight (e.g. the threat quantum computing poses to current encryption). You link multiple ideas into one coherent discussion and use specific examples from the exam materials (like diagrams) to anchor your answers.
