WACE Economics ATAR common mistakes

WACE Economics ATAR · Understand the traps and how to avoid them.

Mistake 1

Defining a term such as 'opportunity cost' or 'structural unemployment' by restating the term in other words, or giving an everyday example with no economic mechanism, instead of stating the precise concept and its conditions.

Students memorise labels from glossaries and class notes but never practise writing a full definition, so under time pressure they produce a circular or example-only answer that gains no definitional marks.

What to do instead

Build a one-line definition card for every syllabus term in the form 'definition + key condition + one contrasting case', and self-test by writing definitions from memory, then checking them against the syllabus wording.

Mistake 2

Describing what happens in a scenario (for example, 'the price of the good rises') without identifying the cause-and-effect chain linking the policy or event to the outcome through a specific economic mechanism.

Students confuse narration of events with economic analysis; they have read the stimulus and can see the outcome but have not been trained to insert the intermediate steps that carry the analytical marks.

What to do instead

Practise writing every explanation as an explicit chain: event, then the shift in a named variable (demand, supply, cost, incentive), then the decision change by a named agent, then the outcome. Aim for at least three links before stating the result.

Mistake 3

Drawing or describing a demand-and-supply diagram where the curve that should shift is moved, both curves are shifted, or the axis labels and equilibrium points are omitted, then describing the diagram incorrectly in the text.

Students learn diagram shapes separately from the underlying theory, so they recall the picture but not which determinant moves which curve, and they do not rehearse labelling under exam conditions.

What to do instead

For each determinant, rehearse the rule 'price changes cause movements along; non-price determinants shift the curve', and practise a set of quick sketches that always label both axes, both curves, the original and new equilibrium, and the direction of change.

Mistake 4

Ignoring the quantitative data supplied in the question or stimulus and writing a purely theoretical answer, or quoting a figure without interpreting what it implies.

Students treat data questions as optional context, or they lack confidence with percentages and index numbers, so they default to the theory they know better and forfeit application marks.

What to do instead

Adopt a habit of extracting two or three key figures before planning the answer, then writing each figure into a sentence that states the trend, the magnitude and the economic implication. Rehearse percentage change and index-number calculations until they are automatic.

Mistake 5

Producing a one-sided evaluation that lists only benefits of a policy or only costs of a change, with no counter-argument, no conditions under which the conclusion would differ, and no explicit judgement.

Students mistake evaluation for 'giving both sides' in separate paragraphs, or they run out of time and truncate the discussion, so the final judgement that carries the top-band marks is missing.

What to do instead

Use a fixed evaluation template: state the claim, give the strongest opposing consideration, state the condition or assumption that determines which dominates (timeframe, elasticity, scale, distributional effects), then give a clear supported judgement. Practise in timed paragraphs of this shape.

Mistake 6

Confusing related concepts such as fiscal versus monetary policy, demand-pull versus cost-push inflation, or a movement along versus a shift of a curve, and using the wrong one in an otherwise well-written answer.

These concept pairs are taught close together and share vocabulary, so students recognise the terms but have not discriminated between them under pressure, and the error propagates through the whole response.

What to do instead

Create contrast tables for each commonly confused pair with columns for definition, cause, who acts, instrument used and diagram effect, and test yourself by sorting mixed examples into the correct category.

Mistake 7

Writing a conclusion that simply restates the introduction or repeats the body paragraphs, or that introduces a new argument or new evidence at the very end.

Students are taught that conclusions summarise, so they summarise content rather than synthesising a position; some also use the conclusion to squeeze in material they forgot earlier.

What to do instead

Draft conclusions as two sentences: one that weighs the competing considerations already presented, and one that states the judgement and the condition on which it depends. Ban new evidence from the final paragraph in all practice essays.

Mistake 8

Misallocating time so that multiple-choice or short-answer questions consume the time needed for the extended response, leaving the highest-value section answered in note form or not at all.

Students answer in the order printed, get absorbed in early questions, and have never rehearsed the paper under a clock, so they have no internal sense of how long each section should take.

What to do instead

Sit at least two full timed papers before the exam, decide in advance a minute budget per section based on marks, and practise starting the extended response with a brief plan so it can be written quickly and completely.

Mistake 9

Answering the question that was expected rather than the one asked, for example explaining causes of unemployment when the question asks about the effectiveness of a policy response, or ignoring a directive word such as 'discuss' or 'evaluate'.

Under stress students pattern-match to a familiar topic from revision and write the essay they have rehearsed, without decoding the directive word and the specific focus of the question.

What to do instead

Circle the directive word and the subject of the question before planning, then write a one-sentence thesis that answers exactly that question. Check at the end that every paragraph serves that thesis rather than the broader topic.

Mistake 10

Using economic terminology loosely or inconsistently, for example calling any price rise 'inflation', describing a fall in the rate of unemployment as a fall in unemployment, or using 'recession' for a slowdown.

Everyday media usage of economic words differs from syllabus definitions, and students absorb the colloquial meaning without noticing the technical distinction, which costs precision marks in definitions and analysis.

What to do instead

Keep a personal list of terms where everyday and technical meanings diverge, with the precise definition and a correct and incorrect example sentence for each, and review it before every assessment.
