Should my child take AP Micro or AP Macro first?

Either order works and most schools teach them independently. Micro starts with the individual firm and consumer, so students who prefer concrete decision problems often find it the easier entry point; Macro deals in national aggregates. The overlap is limited to supply and demand basics, opportunity cost, and the production possibilities curve.

Can graph-heavy economics really be tutored by voice?

Yes, with paper in front of you. Describing a graph aloud — naming the axes, the curves, and the intersections — is close to what the exam asks you to do in writing, and it exposes gaps that silently copying a diagram hides. Evelyn walks you through each curve step by step and asks you to read values back.

How much of the exam is free response?

The exam has multiple-choice questions and three free-response questions, with one long question and two short ones. The FRQ section rewards correctly labelled graphs and explicit explanations, so sessions spend time on the exact wording and labelling conventions rather than only on getting the right number.

My student understands the concepts but loses points on FRQs. What helps?

Usually the issue is unstated reasoning: writing 'output falls' without saying why, or drawing a graph without labelling the profit-maximising quantity. Sessions practise answering in the cause-and-effect chain the rubric expects, and identifying which parts of a question require a graph versus a sentence.

AP Microeconomics

AP / IB · Social Studies & History

AP Microeconomics is a one-semester college course compressed into a set of models: how individual consumers, firms, and resource markets make decisions at the margin. Nearly every question comes back to comparing marginal benefit with marginal cost, and nearly every free-response question asks you to draw a correctly labelled graph and then read a change off it. This tutoring covers the four market structures, cost curve behaviour, elasticity, welfare analysis, market failure, and factor markets — the firm-level content, not the aggregate demand and national income material that belongs to AP Macroeconomics. Sessions are one-on-one with Evelyn, an AI voice tutor, and work through problems out loud rather than delivering lectures.

What this covers

Cost structure: deriving ATC, AVC, AFC and MC from a total product curve, and explaining why MC cuts ATC and AVC at their minimum points
Perfect competition: the horizontal firm demand curve versus the downward-sloping market curve, short-run profit/loss/shutdown decisions, and entry and exit driving long-run zero economic profit
Monopoly, monopolistic competition and oligopoly: MR below demand, the socially optimal versus profit-maximising output, deadweight loss, price discrimination, and simple 2x2 payoff matrices with dominant strategies and Nash equilibrium
Elasticity calculations: midpoint method for price elasticity of demand, cross-price and income elasticity, and linking elasticity to total revenue and tax incidence
Welfare and market failure: consumer and producer surplus areas, per-unit taxes and subsidies, price floors and ceilings, positive and negative externalities with MSB/MSC curves, public goods and free riding
Factor markets: deriving marginal revenue product, hiring where MRP = MRC, the least-cost combination rule, and the difference between a competitive and a monopsonistic labour market

Where learners get stuck

Treating zero economic profit as failure, or forgetting that implicit costs are part of economic cost: Students carry over accounting intuition from everyday life, where profit means money left over. Once opportunity cost is included, breaking even means the firm is doing exactly as well as its next-best alternative — which is why entry stops.
Using ATC instead of AVC to decide whether a firm shuts down in the short run: Both curves sit below price on the graph and both are 'average' costs, so they blur together. The rule depends on fixed costs being sunk in the short run: if price covers variable cost, staying open loses less than closing.
Confusing the individual firm's demand curve with the market demand curve in perfect competition: The two graphs are drawn side by side with the same axis labels but different scales, and the firm's flat line looks wrong next to a downward-sloping market curve. Students then wrongly draw an MR curve below demand for a price taker.
Reading elasticity off the slope of a straight-line demand curve: Slope is constant along a linear curve but elasticity is not — it falls as you move down. Students who memorise 'flatter means more elastic' misapply it when comparing points on the same curve.

What a session looks like

You talk with Evelyn by voice while keeping paper and pencil beside you. A typical session takes one scenario — a monopolist facing a per-unit tax, say, or a competitive firm in the short run — and has you sketch the graph while describing what you are drawing: which axes, which curves, where they intersect, which rectangle is profit. Evelyn asks you to justify each step in the language AP readers look for, since FRQ points are awarded for correct labelling and for explicit reasoning like 'because MR now exceeds MC at that quantity.' Multiple-choice practice runs faster, with quick numerical work on elasticity, MRP tables, and profit-maximising output. You can bring in a textbook problem, a graded FRQ, or a unit you found confusing.

Helpful to know first

Comfort with linear graphs: reading intercepts, slope, and the area of triangles and rectangles
Basic algebra, including solving two equations for an equilibrium price and quantity
Percentage change calculations, including the midpoint formula
No prior economics course is assumed; AP Macroeconomics is not a prerequisite
