Study / Studying Polish in Poland for a Polish Citizen [7]

Hello,

I am a Polish American whose father is from Poland yet my mother is American. I have already been through the entire citizenship process and I am a confirmed citizen of Poland with a Polish passport. My problem is that my father died when I was 14 and since then I have not spoken Polish. I have looked into Polish classes around Poland yet they are all priced for non-citizens. Are there any resources available for Polish citizens that do not have a sufficient command of the Polish language? I would really like to study at a school like the one in £ódź especially in programs geared towards medical Polish. Does anyone have any ideas or knowledge about what to do?

Thank you in advance.
