Which university to choose if almost unlimited opportunities?
I am a first-year student of a Bachelor's degree at Sciences Po. The system of their undergraduate degree is quite complex, but in short, the first year is multidisciplinary (law, economics, politics, history, sociology), in the second you choose a specialization (I know I am choosing Economics&Sociology), and for the third, you have to go abroad. And this is where I would appreciate your tips and advice.
As of today, I am certain that I will continue with a Master's degree in either economics or finance (I want to apply to econ at LSE, Bocconi, Cambridge, and international finance at HEC Paris) and don't want to continue in academia after that. Therefore, I would like to choose a university for my third year abroad that can be helpful for my future. The options are practically unlimited, or so it seems to me. I have to choose from the partner list of Sciences Po, and colleges such as Harvard, Yale, Stanford... are missing. There is Oxbridge or MIT but no option to study econ (either modern languages or politics). So, I narrowed down the possibilities to Princeton, NYU Stern, Columbia, UC Berkeley, UChicago, UPenn Wharton, LSE (General Course), UCL, Bocconi, and NUS in Singapore.
I am indifferent about location or living costs but mainly concerned with the reputation and how this experience can be useful for my application for a Master. I am aware of the fact that an exchange year is not that important but want to make the best of this opportunity and exploit it for the future (especially considering I don't have to pay the outrageous tuition fees of both UK and US universities). Any advice is truly appreciated and valued. Thank you so much for your time.
