I'm not sure what you are claiming here. Are you saying that I'm wrong in questioning calling KTH "elite" because I used one anecdote in a larger argument?

You can look up the admission statistics yourself: it's very easy to get in to KTH. Maybe there are some programs that are more competitive than others.

When I finished high school, the admission criteria for example Electrical Engineering was roughly "you need a non-failing grade in all high school courses". How is that "elite"? Compare with medical school where it used to be "you need the best grade in every single course otherwise you're not getting in". Or the Opera school where there's an admission test in front of an audience.

I can guarantee that MIT is more difficult to get into than KTH.
