This site contains revision notes for the British A and AS level sociology course, new 2010 specification, all examination boards (Edexcel, RSA and AQA). It's the course that leads to university entrance, though the material here would apply equally to most courses worldwide held at this level.
There are also some mnemonic ideas where appropriate.
The external links are to Wikipedia, meaning one can open them in a new window and, rather than just randomly click through related Wiki topics, actually read the essays and articles in a structured way actually based on the specifications. Though one must bear in mind that anyone can edit a wiki article, so although the resourse is excellent to find new ideas, usable quotes and comparative reading, it is, obviously, a first source of reference.
