In general, I agree with the other comments here. It's a weird category, with a lot of different facets.
I'd definitely support Museum Island in Berlin - not necessarily for Educational aspects, but for being a series of monuments purposefully built as museums (instead of being existing buildings that were reconfigured to act as museums, such as the Louvre). Basically, it created an island of knowledge in the middle of Berlin, which seems quite unique to me.
Jantar Mantar is another one I would unequivocally support, for a pre-industrial astronomical site.
With regards to universities: Alcalá, Salamanca, Coimbra all have merits, but the true university cities that would deserve "Top 200" status are Oxford and Cambridge, in my opinion, which are not on the list. So I'd select none of them.
For the modernist buildings, the educational aspect is not the most relevant aspect I believe. Bauhaus is certainly an important site - I'm hesitating a bit with Tel Aviv. Between UNAM and Caracas: the Central library of UNAM is of course well-known, but the University City of Caracas overall looks more spectacular... so undecided between them.
