Not hope he settles and finds some friends soon.
I did find though that some people who were life and soul during Freshers' Week then retreated and you hardly saw them again, whereas some who hardly appeared in the first fortnight found their crowd and were then happy.
I'm dreading dd deciding it's easier to retreat. She'd be perfectly happy in some ways, but she'd miss out on so much. She has got a couple of societies she's interested in, so hopefully that'll give her a drive to get out.
Going back to state/private schools. I went to Oxford, where you might think it was an issue, but never found it an issue.
Ice breaking questions were: Name, college, subject, A-level subjects (grades were never brought up) and where you came from. You got asked those a lot in the first couple of weeks. If people knew the area they might ask which school you went to, but not generally, and I don't ever remember any discussion about whether the school was state or private.
And the name, unless it is well-known, doesn't give away if it's private/state.
After the first couple of weeks it was pretty much forgotten; I have absolutely no idea whether my friends, even those that I've kept up with, were state or private except for a few cases (dh being one) which have been where it's come up (eg mutual friend sending dc to the same places)
The only thing that could be relevant to dd is that I've said to her not to feel like she has to match spending if her flatmates have plenty more money, nor feel she has to subsidise them in the (unlikely) event of her having more money, but if there is someone struggling financially to be tactful and not push them to spend more than they're willing. The latter's pretty unlikely, as she won't have spare money and she's very careful with spending.
