I did my AS Sociology exam 2 years ago but resat unit 1 last year. I had a feeling social policy would come up so I wrote this essay and memorised it for the exam. My teacher marked it 22/24, and I got a high B grade in this exam as a similar question came up and obviously you only have around 30 minutes to answer the essay. Everything that you need to know is in this essay, evidently you can add more of your own points for A03 as I was never good at it, but I hope it helps you in some way! I achieved 310 UMS in my overall A Level Sociology last year. :)
