I provide Psychology (AQA) and Politics (Edexcel) A-Level revision notes by topic, both of which I have an A* in. These notes helped me get it and they can help you too! Although the Politics notes are the 2008 specification, the examples are all up to date and relevant for an assessment of American politics. I'm currently studying at Durham and I achieved 3A* at A level in Biology, Politics, and Psychology.
