Iteration (repetition)
Term Y11 Programming Fundamentals
Definition
A control structure that repeats statements while or until a condition: pre-test loop (WHILE ... ENDWHILE), post-test loop (REPEAT ... UNTIL) or counted loop (FOR ... NEXT).
Example: FOR each item in the array: total = total + item.
Found in: syllabus, school notes, past SDD papers.

- Python: for / while loops
- Drawing: flowchart loop
- Multiple choice: Pick the option that matches the definition or example.

How to use it in an answer
A model sentence
“A control structure that repeats statements while or until a condition: pre-test loop (WHILE ...” Then apply it: FOR each item in the array: total = total + item.
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
- Pseudocode: Write HSC-style pseudocode: capital keywords, paired END words, indentation; initialise variables; output the required result.
- Python: Write code that runs: indentation, quotes, define functions before calling them, print the required output, meet every listed requirement.
- 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.
What the marking guidelines and feedback say
Marker feedback: use pseudocode control structures accurately; iterate an array and sum it; apply relational operators correctly; use the stimulus to choose the right structures.
FLAG: the NESA sample tests pos (0 to 24) against numbers 1 to 25, so it is off by one (25 is never marked, 0 never appears). Safer: test pos + 1 in randList. Marker feedback: replicate the grid; use the random library; use selection and looping to access the list; include a method of checking the number of values; use meaningful variable names and constants; avoid overly complex structures such as nested IF loops.
Common mistakes
- Pseudocode questions (2025 HSC exam Q17): use pseudocode control structures accurately; iterate an array and sum it; apply relational operators correctly; use the stimulus to choose the right structures.
- Python questions (2025 HSC exam Q19): process string inputs; use a selection structure; code must execute in the environment; use correct indentation; call functions in the main program after defining them.
- Python questions (2025 HSC exam Q26): replicate the grid; use the random library; use selection and looping to access the list; include a method of checking the number of values; use meaningful variable names and constants; avoid overly complex structures such as nested IF loops.
- 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.
