Question: My son has been waitlisted by the University of Michigan, so I would like to know if Michigan is accepting applicants off the waitlist this year. Also, when do they start taking people off the waitlist?
This is a question for U. of Michigan, not "The Dean." You should feel free to contact the admission office and ask about waitlist plans. You may get an answer that isn't completely specific (e.g., "We do expect to make some offers of admission") rather than a very clear one ("We have 17 places open right now") but at least the response you receive should put you in the ballpark.
