I wonder how many students would have deferred their places for a year if it had been spelt out: "we'll put you into a shared flat with 5 strangers, and even if you don't get on with them, or they form a clique with you excluded, you will be able to socialise with no-one else, and you will have to sleep there every night for the next year without even coming home for Christmas".
Alternative view if universities HAD gone online:
I wonder how many students would have rather have seen uni go online at home, if it had been spelt out: "You can study in the same bedroom you've been stuck in for the last six months, with your mum nagging you about how you going to the pub puts the whole family at risk. You can stay in your same area and see the same people who you grew to hate at school (only at a 2m distance, mind!). We'll do it online til Xmas but more than likely we'll get to January and the situation will be worse not better, so then we'll cancel you going for the second semester as well and bingo, you can spend your whole first year at home and miss out forever on the experience of living in halls. Then, next year, you can do a pot luck on the house you rent (because the halls will be full of first years) and the random strangers you find online to move in with you.
Yes, you can wait a year to start if you like, but you can't work because there are no jobs and you can't travel because of Covid. And with those dodgy A-levels results which weren't quite what you were expecting, you'll have to reapply and take your chances with an even bigger cohort next year"
Given all this, my DC chose to go in person to Uni this year and is happy to take the chance of getting sick and being locked in for a while if need be, given the alternative of a long lonely winter at home.
I am always struck on Mumsnet at how posters seem to have a very middle aged and practical view of what's best for their teens - some teens will agree, but I suspect a majority would make a different decision to their parents' suggestion that they'd be better off online at home. At 18 it's about independence and fun, rather than getting value for money and enjoying home comforts.
