Chances of acceptance

Hi All,

I was originally going to take my MCATS this fall, as I finish my last year of Bachelors. I went to a two year school for Nursing after HS. And then went on to work. As I worked the last two years, I have decided I want to do more then nursing. So the plan was to finish Bachelors (one more year), take MCATS and apply to Poznan. Well turns other then the Bachelors, I still need to take a year of physics.
SOoooo... this is kind of last minute as I know my chances are not the best as I am doing this last minute, but I have nothing to lose. I am going to apply to the 6 year MD program for this coming fall. I have gpa of 3.1, ton of volunteer work as well as vast amount experience in the medical community as I have worked as a nurse for a couple of years, and prior to that as a technician. I have the motivation and the brains to do this. But I have never taken ACT/SAT exams, so I will have to take the internal test during the interview process (granted I get one). Any one have any recommendation on what to use as a study tool for this test? Or any tips in increase my chances of getting in, other than recommendation letters and maybe a supplemental letter explaining my last minute application.

Thanks in advance for any advice.
