Nope. I don't believe it. How did your daughter do last year? Do you really think it was blind luck, and that it could have been her, or any random 4 out of 5 applicants, at each of the schools? Have you or anyone in your family every been that lucky before in anything in your lives?
You should be "proud of your kid" because what she achieved was a genuine accomplishment, not a result of blind luck after weeding out the unqualified 20%. And of the unlucky 60%, only 1/3 of them were unqualified, and the rest just had really bad luck, everywhere?
I don't mean to suggest that everyone who is rejected could not be successful in med school. But I am definitely saying that, other than at the margins, admissions is not a random lottery as you are suggesting.
