I searched for Poland in all the categories, including by subject and by region, and I couldn't find one Polish university.
As far as I recall, there's not one public university in the top 500 in the world.
On the other hand, the Financial Times listed Kozminski (?) University as #39 in European business schools. Haven't heard of that school.
Yep, it's not a bad place. Well known as the place to go if you want to meet the movers and shakers in Poland.
