EPQ question ideasWatch
As you can see some of them are quite broad and some of them cover incredibly niche topics. I would say choose something that really interests you and you genuinely want to research or it will become very boring very fast. Also don't feel the need to write it all. Simply choosing a topic/ question, reading some books and doing a vague plan will put you miles ahead of your peers. I think my title was something like 'To what extent do authoritarian and permissive parenting styles have an effect on adult psychological state and which is more damaging?'
