How to use it in an answer
A model sentence
Diagram: “A filled circle indicates a flag or control variable passed between subroutines.” Then apply it: Filled circle labelled Found.
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.
Technique for the question types
- Drawing: Use the online drawing tool: label every symbol and arrow, use the correct symbols from the specification, and add every required item.
- Multiple choice: Read all four options, rule out wrong ones, pick one; no penalty for guessing so never leave blank.
- Matching or table: Tick or match each statement to the right column (for example ORM v SQL, SAST v DAST).
What the marking guidelines and feedback say
Know the notation: rectangle = module; arrow with open circle = data couple; arrow with filled circle = control flag; diamond = selection; curved arrow = iteration.
Common mistakes
- Drawing questions (2025 HSC exam Q22): refine attributes into separate inherited classes; use appropriate class diagram symbols.
- 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.
