How to use it in an answer

A model sentence

General advice, built from the definition and example above

“Diagrams that show structure, data or behaviour of a solution: DFDs, structure charts, class diagrams, ERDs, decision trees, storyboards and flowcharts.” Then apply it: A DFD models the flow of data.

In a short answer, give the definition in your own words first, then tie it to the situation in the question. Do not copy the example above unless it fits the scenario.

Command words used with it

General advice

No linked question shows the command word for this term. Across the past drawing and short answer questions in this bank the words used most are: Explain, Outline, Describe, Compare, Classify, Analyse. Check the actual word in your question.

Technique for the question types

Common mistakes

Marker feedback on other questions of the same type (code and diagram feedback often applies across questions)
  • Drawing questions (2025 HSC exam Q22): refine attributes into separate inherited classes; use appropriate class diagram symbols.
General advice
  • Use the term exactly as the syllabus words it, then link it to the scenario in the question; the 2025 feedback repeatedly rewards using the stimulus.
  • Answer the command word: outline gives main points only, explain gives a reason or cause, discuss gives both sides.
