Choose what to work on

HKDSE Economics revision starts with the task you find difficult.

A change in demand is not a change in quantity demanded. Before drawing a curve, identify whether the price of the good or another determinant has changed.

Step 3

Practise the reasoning again

Start with an answer that shifts demand when the question changes only the good’s own price. After discussing it, attempt another example independently.

Keep the learning loop concrete
  • Attempt a task before asking for the explanation.
  • Identify the first step you cannot justify.
  • Try a new task and compare your reasoning.
Know the assessment

HKDSE Economics needs the right kind of practice.

Assessment includes questions testing knowledge, analysis and higher-order thinking.

Precise economic reasoning from evidence

A change in demand is not a change in quantity demanded. Before drawing a curve, identify whether the price of the good or another determinant has changed.

Match the paper requirements

Practise short reasoning chains and longer applied responses.

Practise independently

Use the current framework for paper structure and syllabus scope.

Use the current assessment framework. Tutoring feedback is a study aid, not an official grade.
A revision example

Look at the reasoning, one step at a time.

Identify the changing variable, compare movement and shift, then explain the new equilibrium using labelled axes.

Illustrative learning scenario

Only the price of a good falls; other demand determinants are unchanged. Does the demand curve shift?

Try the task before opening the explanation. Then compare each step with your own reasoning.

Original teaching scenario by AskSia. This is not an official examination question or an official marked answer.

1Identify what changes
The good’s own price changes.
Identify what the task asks before choosing a method.
2Apply the distinction
In the standard demand model, this causes movement along the existing demand curve.
Check this step against the quantities or evidence given.
3Describe quantity demanded
With a downward-sloping demand curve, the lower price corresponds to a higher quantity demanded.
Keep the calculation or explanation tied to the task.
4Check the wording
A change in demand refers to a shift caused by another determinant. Do not use “demand increases” as a substitute for the more precise change in quantity demanded here.
Try another example without looking at this explanation.
