Start by picking a topic from either that you enjoy. It is probably quite easy to intertwine the two in analysing themes in a certain book, say.
Worry about what your question should be after you've done some reading.
I have just started EPQ but really struggling on choosing a title, and all my class has found it easy. I am wanting to do something either psychology or English related, preferably I could intertwine both, as I cannot decide whether to do psychology or English at Uni. any ideas for EPQ titles?
If you cant decide then you just need to read articles that concern Psychology and or English and keep jotting down ideas. More articles you read, then the more knowledgeable you will become. The value of English in Psych or Psych in English lit or studies?
