This is good advice.
The moral of this story is that, unless you are very comfortably off and can afford to subsidise all of your children to do any type of course of any length anywhere in the Uk
You need to sit down with them and talk hard cash, ideally at the stage when they choose their A levels, NOT when they are filling in their UCAS form.
They need to have a realistic idea of what you as a family can afford and what they will need to pay for themselves
what grants / loans / bursaries they are likely to get ( they can work this out on the websites)
the relative cost of accommodation in different cities
the length of their course
the amount of work on their course , length of term and how easy or otherwise it will be to have a part time job
the family’s ability / attitude to subsiding them . Everyone has different views and values about this - some families are happy to take on extra hours / jobs so their kids don’t have to work, other will subsidise vocational courses but not others , some have plenty cash and are happy to support their kids to have fun for a few years.
They need to know all this before they set their hearts on some option that simply doesn’t fit within their budget. And you as a parent need to encourage them to be flexible and not reject good options because they are a three hour bus journey away or “ none of their friends are going there “.
I see too many parents , especially in the south east of England ( where accommodation is expensive and outlooks are narrow ), saying that their children can’t possibly go to eg Leeds or Cardiff because “ it’s so far away “.
And instead they end up spending two hour a day commuting across London and staying in halls where there is no sense of community because there are students from many institutions. And it’s hard for them to have any social life because of their commute.
But at least they have never had to travel north of Watford
