I’ve just finished year 13 and did sociology (AQA). I found it really interesting due to how relevant it is, such as the education chapter. Most of the content is straightforward to understand and more difficult content can be understood with a bit more focus. I found that with essays, your technique will develop over time and once you know how the core debates you can achieve high marks
Hope this helps and I’m happy to answer any specific questions you have about sociology in general or revision or whatever
