Maybe they are willing to move so they are asking which ones people know are great for dental students.
To answer your question OP, I have heard that Midwestern AZ biomedical or something masters is really good and you are 95% guaranteed to get into Midwestern AZ upon successful completion. If you applied to Colorado and get rejected, they have a post bacc program for rejected students. Essentially you do one year of post bacc mostly upper division classes and you are guaranteed a seat in the following entering class.
