Study / Graduate school in mathematics as foreign student in Poland [2]

Hello. I am an American interested in doing a masters in math in Poland. Are prestigious universities like the University of Warsaw and Jagiellonian University out of my league? I received a B.S. in mathematics (honors track concentration) from the University of Notre Dame (a top-20 American university), did a lot of graduate theology coursework, and graduated with a 3.4 GPA. I have been tutoring since graduation because of family reasons. Do you think these universities are out of my reach? They're the best schools in the country so I wonder if I should even bother, given my lackluster GPA. Can anyone speak to the quality (and selectivity) of the programs there, or at other Polish universities where they studied math? Feel free to add anything about grad school in Poland in general. Thank you :)

P.S. I intend to move to Poland someday, so going to grad school there just seems like the logical first step on that path.
