I also don't think you'd be applying both to Anglia Ruskin and Cambridge,
Except for Medicine, perhaps? But that is based at ARU in Chelmsford, I suppose.
I think schools have to take some responsibility in not encouraging mad, far-flung choices. Train fares and petrol costs can be prohibitive these days.
I'd like to think that schools would carry on advising students to aspire to finding the 'next step' - be it full time employment, apprenticeship or university - that is right for them on as many levels as possible.
DD has just gone off to the University of Birmingham, just ove 160 miles from home. Her older brother graduated from there in 2018 and has stayed in the local area. DS2 will be leaving school in 2021 - he currently wants to study History of Art. The nearest places to do this, are the Courtauld, Cambridge, Kent and UEA, in that order (I think - the Courtauld is under 40 miles, UEA, 100). His current dream university is UEA, but he may give Cambridge a go if he likes the look of the course. Absolutely zero pressure from us to do anything in particular and his grammar school is heavily supportive of apprenticeships, so unlikely to be too much from there, except to make sure that he makes the best decision for him.
