I did A levels last year and did sociology so if you had any specific questions about it I'd be happy to answer them.
In general, although slightly content heavy, most the content is straightforward to get your head around. It is an essay based subject which is something to consider though I'd say that it is less so than subjects such as history and english and for me, I found that the fact that there was no coursework suited me well though you may want to consider whether you want a subject that focuses less on exams. I really enjoyed the subject due to how relevant the topics, such as education, are
Hope this helps
