Lily, I am not sure you can describe it as elitist. That certainly was not DS’ experience. There were presumably some very rich overseas students but the ones DS hung out with weren’t. Some were Eastern European in the days when EU students did not pay fees and very bright but not well off at all. Whilst Asian students were often on ‘family scholarships’ where family would club together to pay for a bright kid to have a world class education. Several of DS’ overseas friends would save money by sharing rooms in rental flats. They ate cheaply, China Town is near by and tended to cook in groups. DDs flatmates in her Bristol first year appeared to have far more disposable income for regular clubbing, Deliveroo, coffees out etc. International students at LSE are paying a lot for their education, often with their families making significant sacrifices. They can be very focused on their studies, which suited DS as he was absolutely absorbed in his subject and liked having interesting teachers and like minded friends.
If your niece is more interested in a traditional student party life style then LSE is probably the wrong place. Equally if she want to stay in her social comfort zone and hang out with people from similar backgrounds, what ever her background is, then LSE’s diversity might be overwhelming. DS went to Seoul during his first summer to visit a school friend, but caught up with one of his LSE friends as well. It turned out that this boy’s dad was very senior in Samsung so DS got the full Gangnam tour, VIP rooms in trendy night clubs etc. DS was absolutely not aware. In London they both studied hard and were doing well and this, rather than relative wealth, is what they had in common.
I am not sure I buy this ‘better for PG’ idea. Being a PG at LSE is very expensive (I think DS paid £23,000 for 10 months and this was a few years ago and despite a returning student discount.) courses can then be extremely intense as students know where they want to go and want to ensure that they do well enough to ensure the right doors open. UG suited him as he loved being surrounded by hard working motivated students, as well as the sense of being at an international crossroads, both for staff and students. With caveats. You do need to be motivated and a self starter. LSE welfare is better than, say, Bristol where you could disappear without trace and no one might notice, but living on your own in London is a challenge. Ultimately this is the decision.
