The reality is that most courses at most universities will take/make offers to anyone who meets their minimum grade requirements. In fact many will take students who don’t make their grade requirements. These courses don’t care what you write in your PS, they want bums on seats or £ in the bank. (When unis write to prospective students referencing their PS to say how much they hope they will accept their offer they’re in marketing mode, it’s not because your DC wrote the most amazing PS. Yes, they’ve read it, but they’ll be sending that letter to everyone, it’s not a value judgement. Sorry but that’s the reality.)
Even at Oxbridge, for science courses, they don’t care about PS. They look at grades, admission tests and performance in interviews - which are entirely problem based.(They will say they look at PS but as long as you can write a few sentences about a book/course/competition/project you did, you will be fine, they are not making final offer decisions on the basis of PS.)
It’s a farce which universities participate in because they don’t want to admit the true situation: in the main they are desperate for students.
A few massively over subscribed courses do have to make selection decisions on the basis of the info in front of them and maybe for some that will include the PS, but a PS will not trump the highest predicted grades or some contextual info. (A further extension of the farce is unis - I’m looking at you LSE - who explicitly tell students that they didn’t get offers because on their PS.)
I know an admissions tutor at a top uni where they take students who have missed their offer rather than go into clearing. At that point they pick the students who will tick the most boxes on their widening participation criteria. They don't look at the PS - despite what they say at open days.
The amount of time, resources, webinars, open day presentations that are spent on the PS are completely disproportionate to its value. Students would spend their time more wisely improving their A level grades. Universities should step up and be honest about this.
AI just makes this all the more obvious.
Yes, on a few courses, at a few universities where there are interviews, the PS may be a useful ice breaker, but to really test students interviewers need to get candidates off their prepared material and into the unknown and unfamiliar, so even there, the value is marginal.
[The only exceptions are highly vocational courses like medicine where they want to see specific experience.]
