UK LLM programs are overall much less taxing and rigorous than US LLM programs (especially from a T6 US law school). UK LLM programs (not counting Oxbridge) also accept people more easily - the basic filter level is lower. So that's not very surprising.
look some of it is class and caste positionality. some of it is kids being idiots. you are talking about 18 year olds they have a lot of growing up to do. Some of it is also that the LLM programme is usually not very rigorous and admit standards are on the floor. that is changing slowly, but consider that for these students a big part of their identity is that they are doing to fairly intense law programme and they are learning things everyday and "achieving" things in terms of publications, moots, debates what have you. if LLM students also start to publish in the same journals, moot, win debates, they might have less reason to judge you. demand that your institution not treat you as step children, work your butt off.
It is not about the cost being low (so the question of affording LL.M. abroad does not arise). The LL.M. programmes in India are quite literally a joke.
This is very sad and unfortunate. Shockingly, even first year students of some law schools look down on them and mock them. It is very mean. The majority of people in India cannot afford to do an LLM abroad.
So that's not very surprising.
