i am currently at the first faculty of medicine, charles university in prague. i am loving it here. i would be happy to answer any questions you may have. just some words of advice, first...whatever you decide about med school here, avoid the programs that use agents. as far as i know, the prague faculties do not use agents, and i do not know about the polish programs. i do know that the agents will fleece you and mislead you about the programs, wherever they may be.
another note is, stick with the 6 year programs. the educational model in europe is based on a 6 year program, and it is different then the US model. the 4 year programs are not what they are used to doing, and it also does not give you enough time to learn the language.
but, living in europe is awesome, and it is one big reason why i am here. i did not want to do the island thing, and being here gives you access to so much. also, the education is very strong. they have been educating doctors for hundreds of years and doing it well. grear hospitals with tons of excellent clinical exposure. and, if you want to rotate to the US, we have exchange agreements with several major US med schools. if you are more interested in rotating through Europe, they have the Erasmus/Socrates program which allows you to do semesters at nearly every school in Europe.
So, upside is that it is a serious education in a great location, cheap. Downside is learning the language (not too bad), longer program (but all summers off), and it is not tailored to USMLE. If it sounds like a good fit, visit the schools if you can! Good luck and let me know if you need contact info or a tour guide when you get here!
