I don’t know about psych, but for sociology, it would be a pretty big challenge in a year. Everyone always assumes it’s “easy” but there is A LOT of content, and it takes time to develop your exam technique because it’s so specific. I’m not saying it’s impossible, but you‘d have to put a considerable amount of work in to do it in half the time.

Paper 1: Education, theories and methods in context
Paper 2: Two chosen topic, the most popular being Families and Households, and Beliefs in society
Paper 3: Crime and deviance, theories and methods
