Build an exam prep pack from your lecture notes

Attach lecture notes, slides or a textbook chapter. Get a study plan, key concepts, flashcards and a practice test with an answer key.

How to use it

  1. Attach your material PDF, DOCX, notes — or photos of handwritten pages.
  2. Say when the exam is The plan is scheduled backwards from the date.
  3. Practise, then ask for more Take the test, then ask for a harder one or an explanation of what you missed.

Return:

  • A day-by-day study plan that fits my time, with the hard topics earlier and a review day before the exam.
  • The ten most important concepts, each explained in two plain sentences.
  • Twelve flashcards as a table: question, answer.
  • A practice test of eight questions (mixed types) and a separate answer key with short explanations.
  • Three common mistakes students make on this material.

Base everything on the attached material. If it does not cover something an exam on this subject would, say so.

Ten key concepts

  1. Opportunity cost — what you give up to get something. The true cost of any choice.
  2. Price elasticity of demand — how much quantity falls when price rises. Above 1 = elastic.
  3. Marginal revenue vs marginal cost — a firm maximises profit where they are equal.
  4. Monopoly — one seller who can set price above marginal cost, creating deadweight loss.
  5. (…six more in the full pack)

Flashcards (sample)

QuestionAnswer
If price rises 10% and quantity falls 20%, what is elasticity?2 (elastic)
Why does a monopolist produce less than a competitive market?It must lower price to sell more, so marginal revenue is below price
What is a Nash equilibrium?Each player's best response given the others' choices

Practice test (sample questions)

  1. Demand: Q = 100 − 2P. Find elasticity at P = 20. (calculation)
  2. True or false: a perfectly competitive firm is a price taker. (true/false)
  3. Explain why a cartel is unstable. (short answer)

Answer key (sample)

  1. Q = 60, slope −2 → |E| = 2 × 20 / 60 = 0.67 (inelastic).
  2. True — it takes the market price as given.
  3. Each member gains by secretly producing more while others keep to the quota.

Common mistakes

  • Mixing up movement along the curve with a shift of the curve.
  • Using average cost instead of marginal cost when finding the profit-maximising output.
  • Forgetting to check whether elasticity is calculated in absolute value.
