Both @Wooky073and @Kurkara make very sensible points about the realities of universities and how they really are as businesses. Really important to understand. (TBH if they hadn't become like this, Ds might have got in, but I wouldn't have.)
Working out a future for a YA with ASD and ADHD who's already had difficulties fitting into standard education and situations, and is bright, is hugely difficult.
It's very easy to see x years BA, with a year in industry, followed by y doing a masters and then be accepted to work at z ,as the solution while they mature.
IME universities often encourage it. (not necessarily their lecturers but some tow the line)
When you have a young academically able person, who isn't uniformly able, or at the right maturity progression age wise, and whose future is fragile, it does seem like all the answers to huge challenges in life in one package.
With enough support it can be, but it rarely goes to plan, and you have the pull of 'only good option for them' from one side, and push of 'what's the point, if they have difficulties' from the other.
Many on this thread have absolutely no idea of what's needed to raise YA's with SEN's to an independent successful future, and think folk are either born able, or should be written of. (bet they don't want to pay to support them though!)
While it's an expensive error to find you've used a year of loans funding studying the 'wrong' degree, it isn't a wasted year unless you see education's only purpose as being an investment in order to work in a particular field.
It does get more complicated with two student debt accounts, but is deal able with.
No one here had ever been to university, we didn't personally know people who had. So 'getting it right' and the huge debt, was a big issue, and we fell for several myths university fed us. (families where all have been, have a different but related issue)
Ds then wanting to change course and uni, was very daunting.
Much of what he learnt in his 'wrong' course, he continues to use and apply, his interest in the subject is undamaged. The same for everything he took from his actual degree, though it is more relevant to his (Covid forced) career change.
Once BA became possible, we found huge pressure to continue direct to Masters, and implications he wouldn't do very well without it. Possibly true of his first degree choice, but not his second.
He's now got to a position where he'd need to save up, but funding a masters himself later in the subject he took his degree in, if he wants to undertake one, is possible.
He's also wiser about the importance of putting some years in before doing a Masters, and if actually it's that career progressing in itself, or more an opportunity to take time out to indulge in deep diving in education alongside others, and then possibly be able to use it's 'cachet.'
Has also understood the tempting discount his old uni offers if he took a masters there, doesn't make the quality of their offer better.
Most of all he's realized the only Masters that are worth it in his subject area, aren't in the UK. But no university in this country is ever going to tell him that.
At times, he does get support over work issues from home, as do many NT offspring. No he doesn't need 'mummy' to talk to his work, or negotiate his pay rises. He and others, recognize his worth, as well as difficulties.
