go to this website:
http://www.uwmedicine.org/Education/WWAMI/
should give you everything about the WWAMI program.
but, here it goes.....it's a NW regional med school program. if you sign up for it, you'll do your first year in MT at Montana State University in Bozeman. Second didactic year is done in Seattle. The 3rd and 4th years can be in any of the 5 states designated by the initials above.....
each state designates how many students it will sponsor for this, so you'd have to check the Montana State website, or contact someone in MT for that information.
as for stats.....it's pretty hard to gain acceptance. but, since you'd be considered "in-state," that's good. my advisor said that to get an interview, based on scores alone, you'd have to get a 27 on the MCAT. other than that, earn a good gpa and get some clinical experience (a year's worth or so?)......
hope this helps.
