sounds like a good thing to me...at least they seem very organized and on top of things. i would absolutley ask the cali med board what the status is if you want to work in cali. i talked to the organization out of curiosity when i saw the website, and they were very upfront about what the offered, what they required, etc...i thought that was great.
the polish programs have a 6 year and a 4 year option, but i have seen a lot of negative comments about the schools. 2 students from here were going to transfer, and spent a week in poland only to very quicky return, saying that the 4 year program was not what they expected. personally, i think if you want the 4 year program you should go somewhere that has done it for a while, and modeled it after the US, like the carib programs. the european 6 year programs are awesome, but the schools just don't really know the american system, it seems. but, varna seems good, and the price is right!
i do always encourage folks to really consider whether they want to be among the first grads of a program. ask yourself if it may be a better fit to go with a proven entity, or at the very least be aware that it is a risk to go with a program that has no grads or history to evaluate.
but, all that aside, these guys are organized, and have some good standards, etc...maybe they will be the ones to make a good 4 year program out of eastern europe, i can't see why not!
good luck!
