If you're interested in Krakow, you should call the school office and speak with them about the MCAT requirement vs. your academic achievement and current situation. They may very well be flexible if you can convince them of your suitability for the program (3.8 GPA + grad student is an excellent start). I believe the MCAT is only listed as required because it is assumed that all applicants from the US will have taken it. I know for a fact there is some play in the recommended requirements, as long is the student is clearly a strong candidate. Good luck wherever you end up.
