I agree with swing that most aspiring medics will struggle with one element of the application process, whilst finding others straightforward. DD had no problem with grades, interviews, or filling out her PS with lots of relevent stuff. UKCAT was her problem.
And its here that I have an argument. As earlier posters suggest, many medical schools have a UKCAT cut-off hovering around the 670 mark. Sub-optimal conditions at a test centre, or simply an off day, might easily push results down 10 marks. I would also argue that extra time, given the test itself is long, does little to level the playing field for those with SEN. 10 few marks and a score around the 660 mark can mean no interviews, rather than the four that applicants with 670 have received. Yes, you might have a bad station at an MMI, but hopefully you shine at your second interview.
I think it also presents a problem for medical schools, as it means that they are all fishing from the same pond, and catching the same applicants. An applicant who has four interviews will attend in case they need a fall back. An applicant with one is almost certain to take up any offer.
And what is UKCAT testing? We know a couple who got almost top marks. One practiced every day for six months - in fairness he had an odd mix of A levels so was limited in where he could apply so could not afford to leave his UKCAT score to chance. Another was fearsomely bright but not an obvious medic. He happily admitted he was not interested in medicine, but that this was what his parents wanted and that with his cultural background their views mattered. Even he was bemused to get SJ1. On the margins, informed parents/schools with the ability to pay for/provide tuition will get an applicant those vital 10 marks. And does the UKCAT really deliver the right people, and does it deliver sufficient diversity of skills and aptitudes to match the full range of roles within the NHS? Who decided on the skills that were to be tested, and is anyone looking at the correlation between UKCAT scores and subsequent performance.
Cambridge University have looked at the correlation between BMAT and subsequent performance www.cao.cam.ac.uk/sites/www.cao.cam.ac.uk/files/ar_predictive_effectiveness_of_metrics_in_admission.pdf. Even though BMAT is a more academic test, perhaps linking better with the Cambridge course, the correlation is only described at "positive" not even "good", in contrast to the correlation between GCSE/AS performance and subsequent performance in "Tripos".
I suspect the unpredictability of UKCAT will also hinder aspiring medics from finding the right fit. DD comes from an urban background, she is academic but dyslexic. She learns better by being in a classroom than through self study. She wanted to study in a City, on a reasonably structured course with a relatively academic focus. She made an early decision to only apply to places which had a good fit, even though she recognised that in practice she was only filling in three lines on her UCAS form, and if need be try again this time taking BMAT which was likely to be less tricky. Yes, she may well have got a place at SGUL or Plymouth, and indeed she went to the SGUL open day wanting to like it, but the fit was not there. She was lucky that at the time Bristol did not use UKCAT and prioritised A level predicitons and PS. That door is now closed.
Yes there is luck in the process, but my belief is that the heavy reliance on UKCAT is preventing medical schools from identifying the best applicants and, preventing some of the best applicants from getting places. Perhaps the solution might be to accept that UKCAT is essentially forming a filter function to access NHS training, and to set up a broader, more nuanced and tested filter to include school performance to provide a wider pool of suitable applicants that medical schools can then fish from. In the same way that CSSB identifies and allocates Civil Service trainees.
