I have put a free book of economic notes up online that you can download. They follow the Edexcel Syllabus, but economics is economics, whatever the particular body you are with.
The web site is called "Bucknall's Refuge #2" and it is at:
Free Economics Notes - designed for the GCE A Level
The individual Units can be downloaded separately, or the whole thing as a book.
THE SIX INDIVIDUAL UNITS:
"Unit 1: Markets - How They Work"
"Unit 2: Markets - Why They Fail"
"Unit 3 - Managing the Economy"
"Unit 4 - Industrial Economics"
"Unit 5 - Labour Markets"
"Unit 6 - The United Kingdom in the Global Economy (Foreign Trade)"
I used to tutor in this subject but have given it up. I thought I might turn the notes into a book and publish it, but it became clear that I am too busy to finish it. Rather than just junk the notes, I decided to do the right thing and make them available to YOU!
