Build a Definitions Bank That Actually Earns Marks
Learning objectives
- Explain why precise definitions earn exam marks
- Select the right terms for your definitions bank
- Write definitions with exam-grade precision
- Learn the bank through recall rather than recognition
- Deploy definitions effectively inside answers
Why Definitions Earn Marks
Nearly every economics question rewards or requires definitions: essays open with them, data responses expect key terms defined, and even calculation questions earn marks for stating what is being measured. A precise definition is often the cheapest mark on the paper.
Beyond the direct marks, definitions sharpen everything else. A student who can define elasticity precisely reasons about it precisely; vague definitions produce vague analysis. Your definitions bank is therefore both a mark-earner and a thinking tool.
A definition must distinguish the term from its neighbors: demand is not quantity demanded, a recession is not a depression. Build each definition around what makes the concept unique.
Which Terms Belong in Your Bank
Include every key term from your syllabus that appears in command words or mark schemes: the core concepts (scarcity, opportunity cost, equilibrium), the models' components (marginal cost, aggregate demand), and the easily confused pairs (real vs nominal, fiscal vs monetary).
Do not include everything — a bank of two hundred vague entries is worse than eighty precise ones. Prioritize terms that recur in past papers and terms you personally confuse; the bank should reflect the exam and your weaknesses, not the glossary's length.
How to Write a Precise Definition
Write each definition in one or two sentences using the course's standard phrasing. Start from the textbook definition, then compress it without losing the distinguishing features: what it is, what it measures or describes, and any essential conditions.
Test each definition against its confusable neighbor: does your definition of a shift in demand clearly differ from a movement along the curve? If a classmate could not tell them apart from your definitions, rewrite until they can.
A definition like inflation is when prices go up misses the essential features — a sustained rise in the general price level. Examiners award precision; approximations get no credit.
Learning the Bank: Recall, Not Recognition
Learn definitions by retrieval: cover the definition, read the term, and write or say the definition from memory. Flashcards work perfectly here — term on the front, precise definition on the back — reviewed on a spaced schedule.
Test yourself in both directions occasionally: given the definition, name the term. Exams sometimes describe a concept and ask you to identify it, and reverse recall prepares you for exactly that.
Deploying Definitions in Answers
Open essays and long answers with definitions of the question's key terms — this banks the knowledge marks immediately and frames your analysis. In shorter answers, define a term the first time you use it if it is central to your point.
Weave definitions into analysis rather than listing them: as you apply the concept, state what it means in that context. A definition deployed inside a chain of reasoning earns its mark and strengthens the analysis around it.
Maintaining and Shrinking the Bank
Review the bank weekly, retiring terms you reproduce perfectly three times in a row — they are learned. Promote persistent failures to daily review and rewrite their definitions more distinctively.
In the final week, your active bank should be small: only the terms you still fumble. A shrinking bank is proof of progress, and a short final list is easy to refresh the night before the exam.
Key points
- Definitions earn direct marks and sharpen all analysis
- Prioritize recurring and easily confused terms
- Write one-to-two-sentence definitions with distinguishing features
- Learn by retrieval with flashcards on a spaced schedule
- Open long answers with key definitions
- Shrink the bank as terms become automatic
Common misconceptions
✓ Truth: They also prevent the vagueness that caps analysis marks throughout. Precise terms produce precise reasoning — the benefit compounds across the whole answer.
✓ Truth: Examiners match answers against standard phrasing. Learn the course's accepted definitions first; personal paraphrases risk omitting the features that earn marks.
✓ Truth: Passive pickup produces vague approximations. Deliberate definition practice is a small investment with reliable returns — do not leave it to chance.
Frequently asked questions
How many definitions should I learn?
Aim for the syllabus's key terms — typically well under a hundred for a full course. Quality beats quantity: eighty precise definitions outperform two hundred vague ones.
Should definitions be memorized word for word?
Memorize the distinguishing features and standard phrasing, not necessarily every word. The definition must contain the elements the mark scheme checks — the exact wording can vary slightly.
What if two textbooks define a term differently?
Follow your course's specification and your teacher's usage — that is what the examiner marks against. Note the alternative only to avoid confusion.
How do I handle definitions I keep forgetting?
Rewrite them with a sharper distinguishing feature or a tiny example embedded. The rewrite process itself strengthens memory, and the distinctive version sticks better.
