A Fletcher student here. These IR schools are a wayy to expensive. Good school, lots of orgs to get involved in. But WAAAAAY too expensive for what you get. Professors are difficult to reach, the cohort is too big. Scholarships? Aside from the in house scholarship money, you are looking at a shit load of debt. All puny scholarships on offer are really competitive.
Go to LSE or Grad inst in Geneva or Scinces Po unless you have some compelling other reason, or a trust fund. Don't be like me.
