There is a check list in the unit outline, go through every single one of them, thats the best guide.
If u can draw a diagram and explain everything of the dynamics, it should be ok.
e.g. SUbstitution effect, income effect, things such as changes in price, changes income etc.
Know your IC model, different types of goods preferences etc.
Know your D & S, deadweight loss, consumer and producer surplus. Why are quotas bad? and how does price ceilings and price floors work against surplus?
What do isocost curves represent? why do firms select points that are negatively sloped?? what happens when capital becomes cheaper? or wage lowers??
Know your Total revenue curves, know your cost curves, can u explain how the marginal and average cost curves are derived? Do you know how to derive MR from TR? Why is it that profit maximisation is at MR = MC? Why does the fixed cost curve decrease as output increase?
Also, know your industry structures, PC, Monopolistics, Oiliogopolistic, Monopoly.
What are the charateristics for each market structure?
Why is there a price taker or a price maker ??
Why is the demand curve downward sloping and why is it the average revenue curve for the monopolist?
Why is the demand curve slightly sloping for monopolistic??
Why is there discontinuity in a oliogopolistic AR, MR curve??
How does the game theory work? what is the equilibrium? what is the Nash equilibrium?
What happens in the long run for PC and monopolistic structures? why does this occur? what does this imply about super-normal profits and normal profits?? What are the implications on sunk costs/fixed costs?
What is price discrimination? What is the difference and charateristics of 1st, 2nd and 3rd degree price discrimination?
Is first degree more efficient than 2nd degree? Why do firms practice these discriminatory pricing tools?
Also, i think theres a little bit on market failure, asymmetric information externalities etc. but they were minor in the exams.
Like i said, go through the entire checklist in the unit outline on eac of the topics, if you can know what is the concept, know how to provide a diagram where neccesary and explain the dynamics, you should be fine and get a good pass for it.
Thats off the top of my head, best of luck,
