I find LSE an academically very good and challenging university. It is a kind of place where, if you know how to seize the resources and connections of an institution, you will thrive and benefit from being at LSE. LSE, however, exhibits a quite similar pool of socioeconomic backgrounds and mindsets. Yes it is international, but due to the difficulty of getting in you will find the same busy, self-serving, if bright people on campus.
It is a huge asset that LSE is in London. It is an experience of a lifetime to have your degree blend with one of the most dynamic cities in the world.
If you value social life, chill people- you need to think twice about going. If you value nature and time, think twice. I recommend, however, joining a sports society. And, as always, if you want to see change – be the change.
Also remember, there is no such thing as a right decision. Often, we just need to take a decision – and the make it the right decision as we go along.
