See how Kuest teaches it

It asks before it tells, so you do the thinking and it sticks.

You: Price is $8. The firm's ATC is $10 and AVC is $7. Should it shut down in the short run?
Kuest: First, which costs does the firm still pay in the short run if it shuts down and produces nothing?
You: None. And it's losing $2 on every unit, so it should shut down.
Kuest: It is losing money, but shutting down doesn't make every cost disappear. Fixed costs like rent still have to be paid. At $8, is price covering the variable cost of each unit?
You: Yes, $8 is more than the $7 AVC. So each unit covers its variable cost plus $1 toward fixed costs. It should keep producing, because it loses less than if it shut down.
Kuest: Exactly. In the short run a firm shuts down only when price falls below minimum AVC.

In the short run, keep producing while price covers average variable cost; shut down only when P is below minimum AVC.

The method

How to study Microeconomics with Kuest

Micro is graphs and marginal thinking. Draw every graph yourself from a blank page, label it fully, and explain each change as a chain: what shifts, which way, and what happens to price, quantity and surplus.

  1. Think at the marginTutor chat

    Ask Kuest why firms compare marginal revenue and marginal cost until the idea feels obvious.

  2. Draw the graphs yourselfGraphs

    Plot supply and demand, cost curves and monopoly graphs, then shade surplus and deadweight loss.

  3. Check homework step by stepSnap a photo

    Snap a problem set question and work through it with hints instead of a finished answer.

  4. Memorize the rules that matterFlashcards

    Review rules like MR = MC, the shutdown point and MRP = MRC with spaced flashcards.

  5. Mix the market structuresQuizzes

    Take quizzes that switch between competition, monopoly and oligopoly so you learn to tell them apart.

  6. Practice free responses under timeMock exams

    Answer multi-part questions with graphs in a timed mock exam and see what each part required.

  1. 01Scarcity, PPCs and comparative advantageUse production possibilities curves to show trade-offs and who should specialize
  2. 02Supply, demand and equilibriumPredict how shifts change equilibrium price and quantity
  3. 03ElasticityCalculate price, income and cross-price elasticity and link them to total revenue
  4. 04Surplus, price controls and taxesMeasure consumer and producer surplus and find deadweight loss from ceilings, floors and taxes
  5. 05Production and costsRead marginal, average and total cost curves and explain diminishing marginal returns
  6. 06Perfect competitionFind profit-maximizing output, the shutdown point and long-run equilibrium
  7. 07Monopoly and price discriminationExplain why a monopoly restricts output and how price discrimination changes surplus
  8. 08Oligopoly and monopolistic competitionSolve payoff matrices with game theory and explain long-run outcomes in monopolistic competition
  9. 09Factor marketsUse MRP = MRC to decide how many workers a firm hires, including under monopsony
  10. 10Market failure and governmentCorrect externalities with taxes or subsidies and explain public goods and inequality
