dont see anything there related to real estate. Though its a very good website related to information on education in Poland.
Yes, is it related ( I didn't know too)
If you are not Polish citizen and apply for some licence or diplom,( for exm. doctor,real estate agent, building administrator and much more) you will need first to have this certificat. If you need exact information you can call there and they will explain everything.
I will tro to find the link and post it .
Have a nice day:)
