I'm just trying to gauge how I should prepare myself for my upcoming MMI. Would it be valuable at all to practice for the "standard" questions (eg: Why do you want to be a doctor? Why this school? Tell me about your research. etc) for an MMI? I know the standard questions will come up in other interviews, but I want to maximize the last few days I have to prepare for this particular format. Would it be more valuable to devote all of my time to reading up on healthcare policy, ethics, etc?
