By swapping, do you means “ dropping out and starting the same course elsewhere next year “ ? Im assuming that’s what you mean and not “ completing first year and then applying to move to another uni for the same course for second year “.
No it’s not easy to drop out and reapply , lots of courses won’t accept anyone who has started the course elsewhere and not completed it. Some of them even state that in the entry requirements.
Unis get evaluated on things like dropout rates , so to be blunt no one wants someone else’s drop out. Of course it’s a different matter if it’s to do with illness or disability.
Yes he can apply through UCAS next year but who will he use as an Academic referee , it can’t be his school, is he going to ask the uni he dropped out of ? How is he going to explain why he left - because he couldn’t make friends or because he didn’t like the schools that other students went to ? That’s just as likely to happen in another uni next year - what will be different ?
Unis don't like it because he’s wasted a place that could have gone to someone else and they will lose that money from SAAS. They work hard to support students so they stay and hopefully do well.
SAAS don’t like it because they have to try and get a terms money back from your son. Yes you can usually get a years extra funding , a plus one year , but it’s not automatic or a free gift. Your son can look on the SAAS website for info on the conditions attached to the his loan / allowance and the rules about not making sufficient progress on the course or withdrawing and paying back his loan. He will need to pay back any over payment for this year, based on his last date of attendance.
It’s not just the money - it’s the effect it will have on his confidence and self esteem.
Dropping out is a serious decision that could have negative consequences for him - it’s not like starting piano lessons and then quitting after a few weeks . It’s only something he should consider after exhausting all other options - especially if he likes the course and it’s just that he’s not made friends yet.
Of course if he’s ill or struggling with the course or his health then he needs to ask for help. I’m not saying he needs to just suck it up . But it should be the last resort if he’s tried everything else, not the first option if it’s not all amazing by week 4 of term 1.
Im sorry if I sound unsympathetic, I’m trying to be supportive. I know not easy as a parent to strike the right balance with support and advice.
