How to study economics at university: a practical guide

By oosync editorial team · Updated 2026-10-14 · 5 min read

Economics asks you to think in three languages at once. There is the language of words, explaining how people, firms and governments behave. There is the language of diagrams, showing supply and demand, costs, markets and the macroeconomy. And there is the language of mathematics, which becomes more important each year. Strong economics students can move between all three: explain a result in words, show it on a diagram and derive it mathematically.

This guide covers what economics assessments usually look like, how to use lectures and readings, the techniques that suit the subject, a weekly routine and an exam-season plan.

What economics assessments usually look like

Common formats include:

• Written exams mixing short problems, diagram questions and essays.
• Multiple-choice tests, particularly in first-year modules.
• Problem sets, with mathematical questions on models.
• Essays and coursework, applying theory to policy questions or real events.
• Econometrics projects, analysing data with statistical software.
• A final-year dissertation in many programmes.

Across these, examiners reward analysis: using the right model, showing it clearly and explaining what it means. Description alone rarely scores well.

What to do with lectures and readings

Lectures and slides

Economics slides usually present a model through a diagram, some equations and a short explanation. When you rebuild your notes, capture each model in all three languages:

1. Words: what the model is about and what it predicts.
2. Diagram: labelled, with an explanation of each curve and what shifts it.
3. Maths: the key equations and how the result is derived.

Add the assumptions the model relies on, because evaluation questions often ask what happens when they fail.

Textbooks

Economics textbooks are often clearer than slides and have plenty of practice problems. Use them to understand models properly, then work through end-of-chapter questions.

Articles and policy readings

For applied modules, readings may include journal articles, policy reports or central bank publications. Note the question, the method, the main findings and how they connect to the models from lectures.

Techniques that suit economics

1. Draw diagrams from memory

Copying a diagram from the slides teaches very little. Instead, practise drawing it on a blank page from memory:

• label both axes
• draw the initial equilibrium
• show the change (a shift, not a movement along a curve, if something other than price has changed)
• mark the new equilibrium
• explain the result in two or three sentences

Then check against your notes. This combines dual coding, pairing a visual representation with a verbal one, with retrieval practice. It is also exactly what many exam questions ask.

2. Solve problems, do not just read solutions

For mathematical economics, attempt every problem before looking at the answer. If you get stuck, look only at the next step, then close the solution and continue. Redo problems you got wrong a few days later. Practice testing is one of the most effective study techniques there is, and in economics that means solving problems.

3. Explain the intuition

After solving a problem or drawing a diagram, explain in plain words why the result happens. Why does a tax on a good with inelastic demand fall mainly on consumers? Why does an increase in government spending have a multiplier effect? Asking why (elaborative interrogation) connects the maths and diagrams to real behaviour, and it is often what separates good exam answers from merely correct ones.

4. Apply models to real events

When you read the news, ask which model explains the story. A central bank raises interest rates: what does your macroeconomics model predict for consumption, investment and the exchange rate? Keep a short log of examples linked to each topic. Applying ideas to new situations deepens understanding and gives you specific evidence for essays.

5. Interleave models

Once you have learned several models, mix practice questions so you must decide which model applies. Exam questions rarely say "use the IS-LM model". Mixed practice, or interleaving, can feel harder but tends to improve your ability to choose the right tool.

6. Flashcards for definitions and conditions

Use spaced-repetition flashcards for definitions, conditions and relationships:

Q: What condition defines the profit-maximising output for a firm? A: Marginal revenue equals marginal cost.

Q: Why is a perfectly competitive firm's demand curve horizontal? A: It is a price taker. It can sell any quantity at the market price but nothing above it.

A weekly routine during term

Exam-season plan

Four weeks out: gather past papers and check the format. List every model and diagram on each module. Audit yourself by drawing and explaining each from memory, and rate your confidence.

Three weeks out: relearn weak models. Work through problem sets again, especially questions you got wrong during term. Update your example log for essay topics.

Two weeks out: do timed past-paper questions, mixing models and question types. Practise essay plans that combine diagrams, intuition and evidence. Keep an error log: wrong model, mislabelled diagram, maths slip, weak explanation, time.

Final week: full timed papers, targeted fixes, light flashcard review and rest.

Common mistakes

• Unlabelled diagrams. Label axes, curves and equilibria every time.
• Confusing shifts with movements. A change in price moves you along a curve. A change in anything else shifts it.
• Memorising diagrams without understanding them. Examiners often change the scenario slightly.
• Avoiding the maths. It becomes central in intermediate modules, so build confidence early.
• Description instead of analysis in essays. Use models to explain and evaluate.
• No real-world evidence. Specific examples strengthen essays considerably.

Using tools sensibly

Economics material mixes text, diagrams and equations, which suits working directly on the page. In oosync you can upload lecture slides and readings, draw and annotate diagrams on the PDF pages with a pen, and circle a confusing graph or step to get an explanation grounded in your own sources. You can also generate flashcards and practice exams from your material, with multiple-choice questions marked automatically. See handwriting on PDFs. As with any subject, the learning happens when you draw, solve and explain yourself.
