Hi I think some of the advice on here about EPQs may be a little out of date. Straight from the horses mouth - when the admissions director from Bath University visited DD’s school he was very clear that the EOQ is something they most definitely do recognise and value. To the extent they will make lower offers to those with an A or A* EPQ.
Up until a couple of years ago, it used to not be taken that seriously as not all schools offered it. But this has now changed.
Cambridge have pointedly changed their admissions advice page only last year to the effect of - “We recognise the EPQ and, although an offer will not be conditional on it, we strongly recommend students do one if at all possible.”
UCL are also very keen on EPQs as stated on a virtual open day.
I think if you go into an EPQ with the attitude that it’s a box-ticking exercise, then obviously, you are likely to lose interest very quickly and drop out. The one my DD did was some 15,000 words long. It took a huge amount of research - I think she had over 350 sources in the reference section. It also acted as a springboard for her because it gave her an idea for a response to an international essay competition question - which she won (out of thousands of entries). Then she wrote another spin-off paper and this was published in a journal. So, the EPQ really inspired her and thanks to the things it led to, her personal statement for uni wrote itself. Unis state they want you to prove interest beyond the curriculum. It’s all very well saying you’ve read this and that, but actually putting pen to paper and synthesising your independent reading into an original and coherent investigation is another matter.
Also, the footnotes for the EPQ are not what you might think. Every footnote is evaluating the source. She had about 700 footnotes. It was a massive undertaking.
She did find the diary a bit “extra”. She enjoyed the presentation. As for deadlines, I don’t remember it being a big deal. They just want to check you’re getting in with something and not leaning it all to the last minute - because you can’t leave it all to the last minute!
