I think in years gone by students cut costs wherever they could @HoldMyLobster! Has your DD gone back to university as yet (sorry if I've missed the relevant update)?
We really did - I had a £2,000 grant to live on, and my rent was £2,000 per year! I had a part time job during term-time, and I paid off my overdraft each year with a summer job.
My daughter's university is not allowing first or second years back until January, in an effort to keep enough rooms for quarantining and isolating. So she's home till January, at least.
A 3rd year friend has invited her to come and live in an apartment in Chicago, but she's hesitant while she waits to see how things play out. The Covid rates were not going the right direction recently, so things need to improve.
Life is OK at home though - her boyfriend is here too, and she has a couple of other friends who couldn't or chose not to go back to college.
