And...here's economics! Economics is a hard subject - even I kinda **** at it. Anyways, this revision guide is based on two CIE textbooks. So yeah.
It contains the following:
Material from the 2012 syllabus
Covers units 4.1 - 4.8 (basically the whole course), including things such as inflation, unemployment, development, economic indicators, GDP, factors of production - you name it!
Detailed explanations and awesome diagrams
And lots more!
Update #1: A crazyass improvement in terms of definitions and stuff thanks to doing hordes of pastpapers recently - I basically cut out some unnecessary things and copied and pasted cambridge answers to some of the definitions and advantages/disadvantages. 'Cause textbook answers are pretty useless if they aren't like the mark scheme's. lol.
Lets hope this gets you your A*/As - And hopefully mine too!
