If you want to learn English in Opole, stay away from Empik. Everybody knows that the teachers are treated like carpet. The DOS gets paid to never be there! The director wants the teachers to do her work and seems incapable of doing anything herself. Empik just want money. As for the quality of learning, look elsewhere...
Isn't that 95% of the so called English language schools in Poland? It certainly is in Wroclaw. Trying to find a good school, a good quality school is trying to find some fresh, healthy and tasty bread in Chata Polska, not an easy task.
So in Wroclaw we can forget: Empik Lektor Profi-Lingua Moose (This is the actual name, I'm not making this up!) Yes school (Krzyki) they like teachers to work for FREE, just google their name to check on their reputation, lol BLC Soho Berlitz Speak Up City English
I could go on, but I just want to give a brief summary
