In response to your question, Polish schools are the cheapest way that i know or have heard of to get an accredited medical degree in the United States, Canadian, and Europe. its more expensive now btw, but still nothing i have heard of is even close. Currently only UJ, is accredited in all 50 states and PUMS is soon to follow. As for europe and Canada the schools are accredited through out. So are polish schools a Value MD, yes in this respect the are GL.

ps. the extra 15k a year maybe worth it somewhere else...
