# AQA Economics Unit 3 - 22nd January 2013 watch

1. Just started this exam thread since I couldn’t find it anywhere else

How is everyone getting on revising?

I’ve finished making notes on all chapters of the book, done tonnes of practice papers, now considering just revising little things like:
•Definitions of key words (for the easy 2/4 marks in the 10/15 mark questions)
•All the different types of diagrams
•Justifications of the shapes of curves (such as the SRATC, kinked demand curve) etc.
•All the different objectives of firms
•Modelling Assumptions (Like perfect competition and perfectly competitive labour markets)
•Causes of certain economic issues (such as monopoly power, barriers to entry, poverty etc.)
•Maybe all of the different equations? (because of calculation in the 5 marker)
•Processes (like cost-benefit analysis)

Also, does anybody know any decent economic news websites preferably relating to our course, because I know sometimes they reward knowledge of current affairs (the only source I have been using is tutor2u’s blogs).

Two particular things which I can’t get my head around in this economic course is:
•What “cost plus pricing” is: I thought it was literally just looking at you’re costs and saying okay, we’ll sell our product at say 50% greater than this to make X supernormal profit.
•Why does MRP=D?
2. I wouldn't bother with the equations there all simple, im doing lots of graph revision practicing them every morning

Yeah true. I think that a possible calculation question could be the Gini coefficient, provided they give us the values of the area and don't expect us to integrate the function! ;D Although this is still incredibly unlikely, because my teacher told me the only calculations they'll give you is in the format "(this number/divided by that number) * 100" - so essentially a percentage question.

yeah, need to be careful with index numbers too
5. Does anyone know how to calculate index numbers..?? Thanks
