If the cost of living crisis was bad enough you needed 30 grand saved up to survive it, I think we'd be seeing rioting in the streets at the least!
That's definitely a lot of money so more than enough for uni purposes (I mean you could potentially use that as a deposit to buy a house!).
Might be worth looking at options for savings accounts, investments and so on to make the most of it if you aren't going the house purchasing route (as if it's just sat in your current account it's probably not doing much there). Obviously though there is risk involved in some of those options so you might want some professional advice on that front too?
