A-level Economics, drawn the way you'll draw it in the exam.
Free lessons made by a teacher. Each one takes a diagram and teaches it in drawing order: watch it drawn, try the key steps, build it, then draw it from memory and mark it yourself.
Free. No account needed. Built around the WJEC and Eduqas specification first.
How a lesson works
The same stages in every lesson. If you have already seen the diagram in class, you can jump straight to Try.
- 1GuessPredict the answer before you watch.
- 2WatchClick through it being drawn in exam order, with the reason for each line.
- 3TryClick the key steps yourself. Marked instantly.
- 4BuildPut it together from the pieces.
- 5DrawDraw it from memory, then mark it against the model.
- 6SpotFind the mistake most students make.
- 7ExplainWrite the chain of reasoning and check it.
After the lesson: a retrieval quiz that comes back when it is due, and an exam question you can type or write on paper and mark against the levels yourself.
Lessons
A2 microeconomics, in the order it is taught. 11 of 20 lessons are open.
Costs, revenue and profit
- 01Short-run costs: MC, AVC and ATCDraw MC as the Nike tick first, then bring AVC and ATC through its lowest point.
- 02Long-run average cost and economies of scaleThe LRAC curve, minimum efficient scale and why firms grow.
- 03Revenue: AR, MR and TRWhy MR falls twice as fast as AR, and why TR peaks where MR is zero.
- 04Profit maximisation at MC = MRNormal profit, abnormal profit and losses on one diagram.
- 05Shutdown points in the short and long runWhy a firm making a loss can still be right to keep producing.
Efficiency and the growth of firms
- 06Productive, allocative, X- and dynamic efficiencyEach type of efficiency marked on the cost curves.
- 07How and why firms growOrganic growth, integration and demergers, as chains of reasoning.
Market structures
- 08Business objectives on one diagramProfit, revenue and sales maximisation marked on one diagram, and why a firm might not maximise profit at all.
- 09Perfect competition: abnormal profit to the long runWhy profit cannot last when anyone can enter the market, and how to draw the adjustment without the usual mistakes.
- 10Perfect competition: losses to the long run through exitMarket and firm side by side: losses, firms leaving, and the price rising back to the bottom of ATC.
- 11Monopoly: profit maximisation and deadweight lossPrice and output at MC = MR, the profit box, why a monopoly is inefficient, and the case for natural monopoly.
- 12Monopoly: price discriminationFour buyers and some simple numbers show why charging different prices raises profit, the three conditions it needs, and who wins and loses.
- 13Monopolistic competition: short run to long-run tangencyHow entry turns short-run profit into the tangency equilibrium, and why that leaves excess capacity.
- 14Barriers to entry and contestabilityEconomies of scale as a barrier, limit pricing, structural and strategic barriers, and the threat of entry.
- 15Oligopoly: concentration ratios and interdependenceCalculate a concentration ratio from real grocery market shares, and see why a few large firms have to watch each other.
- 16Oligopoly: game theory and Nash equilibriumOne payoff matrix, read the same way every time, and why two firms end up cutting price when both would earn more by not.
- 17Oligopoly: collusion, price leadership and price warsThe cartel drawn as a joint monopoly, the welfare it costs, and why each member is tempted to cheat.
- 18Kinked demand (extension)Why prices in an oligopoly can stay put, and the model’s limits. Not named in the WJEC specification: use it for evaluation.
Competition policy and privatisation
- 19Competition policyMergers, cartels and regulation, as chains of reasoning.
- 20Privatisation and regulationThe case for and against private ownership of utilities.
New lessons open as they are taught. Market structures come first, then the rest of A2 micro.
Daily retrieval
Questions come back when you are about to forget them: tomorrow, then in three days, a week, a fortnight. What you know stays secure. What you leave fades, and Review shows you where.
A five-question starter in one click
Tick the topics your class has covered and get a retrieval starter that mixes last lesson, last week and older topics. Project it, reveal the answers, or print it.
Built on what the evidence says works
Every lesson opens with a question, and the ones you get wrong come back later.
The first time, the diagram is drawn for you. By the end of the lesson you draw it alone.
A model answer and the mark scheme levels, not a score from a machine. No streaks, no leaderboards.
