In Unit 1/2 you just create a diagram, say demonstrating AD/AS, and shift the lines if appropriate. Easy.

But these more trickier looking graphs in Unit 3, specially Chapter 3 ('Long-run equilibrium and efficiency') which are involving firms making losses/entering and leaving industry/market response...etc, basically the MC/AVC/D=AR.. curves - are they really necessary to know in-depth and how/will you be required to recreate those in the exam?

If anyone could gimme a heads up on that, I'd really appreciate it. Cheers.
