Not sure why I feel the need to get into this but, in defence of the EPQ....
Firstly, it is a qualification. An A at EPQ is worth exactly half of an A in an A-level in terms of UCAS points. An EPQ also has more weight then an AS level in terms of UCAS points.
Like any qualification, it is only an empty exercise if the student approaches it as such.
Like Vargas, I would say probably half the students who started EPQ at DS’ school ended up dropping out. This suggests that there is slightly more two it than just meeting deadlines.
Some of the EPQ titles I have seen are really original and fantastic actually, and definitely stretch them well beyond the A-level syllabus. Unlike an A-level course, they are not spoon-fed information.
I can really only speak for DS, but I would say his EPQ was far more useful than the qualification itself. It has focused his mind in what he wants to do as his degree. It has showed him the links between two of his A-levels and enabled his to expand into other areas such as anthropology that he wouldn’t otherwise have even known about or considered. Just as importantly, he realised, in the process of writing, that the frontline of research in the areas that motivate him are happening right now at the LSE, UCL and KCL. This has driven his applications to LSE and UCL because the sources he was investigating were written by the actual professors who are there now. The research is contemporary and spans the social sciences and this is where its happening. This is far more of an insight than any open day or prospectus can give them.
Also, off the back of his EPQ he became very interested in another line of enquiry. He wrote an essay for a national competition which he never heard back from, but it still an area of interest beyond A-level and he referenced it in his PS, Then, over lockdown, he wrote another essay inspired by an unfinished line of investigation in his EPQ and he sent this off thinking it would get no feedback, but he did and it’s going to be published in an online journal for undergraduate work / research. None if this would have happened - he wouldn’t have even thought of it - were it not for the EPQ. It’s really focused his mind on what he wants to do in the future.
