Hey! I did the EPQ and it's a bit of a pain while you're doing it but in my opinion, its a very valuable qualification and unis love it. I did an essay so I don't really know much about artefacts but a lot of the teachers at my college said that it's a lot harder to get a high grade when doing an artefact unless you do some sort of art/drama/music subject at college. Some people in my EPQ group wanted to do economics at university and so did their EPQ on how the London Olympic Games financially impacted Britain. Hope this was helpful!
