Revision notes for the Edexcel A-level Economics A course. Includes: Theme 1 - Introduction to markets and market failure Theme 2 - The UK economy Theme 3 - Business behaviour and the labour market Theme 4 - A global perspective I achieved a grade A with these notes and I hope they will help you too. Some of the topics are not in the same order as the specification and a few topic areas are missing from Theme 4. The missing topic areas are: 4.1.3, Pattern of trade, 4.1.5 Trading blocs and the WTO, 4.1.7 Balance of payments, 4.1.9 International competitiveness, 4.2.1 Absolute and relative poverty, 4.4.3 Role of central banks, and all of 4.5. This is because these areas were either not included in the 2022 Advanced Information, so I did not make notes for them, and because the revision for topic 4.5 is basically the same as government policy topics in Theme 2. I hope this is not a major inconvenience.
