I did AQA sociology last year and it's really different from OCR, with AQA you do 2 exam papers at the end of 2 years but with OCR there's 3 which makes it easier because all the information you have to learn isn't as compact. I am doing OCR sociology this year because I am resitting year 12 and the module is better than AQA! I would look on the exam board or your college website for the pass rate for sociology because it is a really hard A level as a exam based subject
