How to use it in an answer

A model sentence

General advice, built from the definition and example above

Code pattern: “import a module to use its functions: import random, import math, from sklearn.linear_model import LinearRegression.” Then apply it: import math

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

Common mistakes

Marker feedback on other questions of the same type (code and diagram feedback often applies across questions)
  • 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.
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.
