I did Sociology, I enjoyed it a lot.
It is a lot of essay writing and remembering so if you aren't good at that maybe steer clear of it.
Although I frequently in exams made up names of people and studies if I had a valid idea I wanted to express but no actually person who conducted a study!
As others say just look at the content availabel at A-level first.
If you like debating and essay writing then it's the thing for you!
