Yes, most schools (MD and DO) will send you a secondary app. so they can collect your $$$. Just the way it is.
DMU does not do this as far as I am aware. As I was told (I'm on the admissions committee), DMU basis its initial screening the same way as any other school... GPA and MCAT scores. However, this has its benefits... if you get a secondary, you are very likely to recieve an interview. The purpose of the interview at DMU is to get to know the applicant and see if they would be a good member of the DMU community.
For what its worth, send in all the secondaries you get... you never know what can happen!
