Personally myself the key to any subject is to learn your key individuals, examples, case studies etc as much as possible. For sociology it is key for you to learn your sociologists and their respective perspectives. For my revision I have a fairly simple method as to how to remember my sociologists.
Firstly, when reading them from my textbook I find it useful to write the name of the sociologist in BOLD or CAPITAL letters to help them stand out for you when re-reading over your notes.
Secondly, I find that making your exercise or text book bright and colourful so it will a. not look so daunting and b. so it will stand out in your mind. I would suggest using a code for certain sections that you highlight for example:
Yellow for key sociologists
Pink for key information
Green for important dates or acts ( for example on the education section in educational policy the 1988 Educational Reform Act ERA)
Blue for perspectives such as functionalists, feminists, marxists or the New Right.
Orange for contrasting beliefs, fir example in family feminists criticise the functionalist social policies as not doing enough for women and the marxists claim that the functionalists don't do enough for the working class.
Hopefully this post and indeed the thread will create some discussion where everyone can take some ideas and use them and perhaps pass them on to others students in their schools and classes.
Best of luck everyone
