DD is in year 11. She is planning on taking Biology, Chemistry and Psychology A levels and I think is unlikely to change these options as she wants to do Medicine. However, she loves Physics and it's such a shame that won't be able to continue it based on her current priorities. She's now thinking she may do an EPQ is Astrophysics (previously she was thinking she's unlikely to do an EPQ but now considering it out of a genuine love of learning about space).
My question is - do students usually pick an EPQ topic based on their future goals, or do they usually pick something unrelated - like in this case - out of an interest in the subject? If she is hoping to pursue Medicine, should her EPQ topic be related to that?
