Is it common for Polish people to speak English in Poland? [122]
Rather not. Few people over 40 speak it at all, even among the well educated.
You seem to be putting the bar at far too high a level.
I personally know a great many people over forty who speak English (imho) well.
Furthermore, I'd suggest far more than 20% of students can speak English well enough to have more than a 'basic' conversation.
It depends how you define 'basic'.
I'm not aware of Poles having a 'terror' of reading English. Probably most Brits and Americans don't read literature for pleasure even in their own language, let alone anyone else's. And if they do, 99% would read in the translation rather than the original.
Given that it is obviously far more difficult to communicate in a second language than in your own, I'd say Poles are (generally) doing pretty well at English.
