Okay, yea that sounds like a good shout, don't bother with Ageing Population and marriage and divorce.
For the childhood part, I haven't got to that bit of the course to revise yet, as I'm an external student re-sitting and can't remember hardly anything from Family so have started again completely haha. Maybe search through google and see what people say about what they think might come up?
For theories like, Marxism, Functionalism, Postmod etc. which do you think might come up?
