How Lumini helps with A-Level Economics
You're facing a 25-mark A-Level Economics essay question on your Mac. The question is about whether a firm should increase prices, and it requires a diagram, analysis, and evaluation. You've drawn a basic supply and demand diagram but you're not sure if you need to show elasticity, consumer/producer surplus, or a monopoly diagram instead. You're also stuck on the evaluation — what's the counterargument?
Lumini sees your essay plan and the question on screen. Hold Ctrl+Option and ask "What diagram should I use for this question?" Lumini reads the question: "The key words are 'should a firm increase prices.' This depends on the price elasticity of demand. You need a diagram showing elastic vs inelastic demand, and then a second diagram showing the impact on total revenue. I'm pointing at the words 'should a firm' — that tells you this is a microeconomics question about revenue, not about market failure or macro policy."
The 25-mark essay structure
A-Level Economics essays follow a specific structure. Lumini teaches you the formula: "Your essay needs four elements for top marks. One: definitions of key terms with examples (2 marks). Two: a clear diagram that's correctly labelled with title, axes, curves, and equilibrium (4 marks). Three: a chain of reasoning — 'this leads to... which causes... resulting in...' (9 marks). Four: evaluation — 'however, this depends on...' with at least two evaluative points (10 marks). Most students lose marks on evaluation. Don't just say 'it depends' — explain what it depends on and why."
For evaluation specifically: "You wrote 'prices might not increase if demand is elastic.' That's a start but it's Level 2. For Level 4 evaluation, you need: 'The impact of a price increase depends on the price elasticity of demand, which itself depends on the availability of substitutes, the proportion of income spent on the good, and the time period. In the short run, demand may be inelastic as consumers cannot easily switch. However, in the long run, new firms may enter the market, increasing the number of substitutes and making demand more elastic.' See the difference?"
Diagrams that get marks
Lumini checks your diagrams against the mark scheme criteria: "Your diagram has the axes labelled correctly (price and quantity) and the curves labelled (D and S). Good. But you need to show the new equilibrium clearly. Label P1, Q1 before the change and P2, Q2 after. Use dotted lines to connect the equilibrium points to the axes. And always give the diagram a title — 'The Impact of an Increase in Demand on Market Equilibrium.' This title alone tells the examiner what you understand."
Example questions to ask Lumini
- "What diagram should I use for this question — and what should I label?"
- "Is my chain of reasoning complete or am I missing a step?"
- "What evaluation points should I include for this topic?"
- "Am I writing analysis or evaluation — what's the difference?"
- "What real-world example should I use for this concept?"
