Dreadful halls experience here too. Parties all nigh4+days a week, incl before exams, and strangers in the ‘flat’ drinking and smoking. Several others who just went home and commuted because they aggro was not worth it so couldn’t even form an alliance with them. Residents team were shockingly ineffectual despite seeing what was going on. We ended up moving her out and into a family flat but she is devastated. We have heard of others having similar experiences and almost choosing not to go back and transferring to a local uni instead.
However, she has heard from lots of friends who are a year or so ahead of her (she is a little older at 20 starting) that the second year is much better. It seems to be when people actually make friends - perhaps because the rose tinted glasses are off and they return feeling older and more pragmatic.
The job situation is very much an issue - can she apply to M&S, tesco etc as they tend to be willing to take you on as you can work both at home and at the uni town? If money is not the motivation and it is about getting work experience for her CV/get out of her room and make friends, then can she volunteer at a charity instead (which may then help get a paid job down the line). This can be useful because they make local non-union friends which can be really healthy.
The second year is also when, having done all the intro modules, they begin to specialise and chose according to interests that have formed in y1 - which is why I think they tend to start forming more friends on the course because they have more in common.
My DD had such high hopes of Uni and London. Is beginning to rebound now that she is doing assignments and prepping for exams from home. She feels guilty that we were locked into a full years rent and that we are out of pocket. Add into that the weight of the student debt when it has been a less than stellar experience is not helping. We are focusing on reassuring her that the money doesn’t matter [may choke on that a bit] and that it’s all part of transitioning to independence.
Sorry, that may not help you at all though!!
