As others have said, NO. Your application is completely separate from the child of the donor’s kid – you don’t get to ride on his coattails because you happen to have attended the same high school. And besides, Harvard has no reason to “hide” the developmental admit, as it happens all the time. If you’re Bill Gates and you’ve given millions to Harvard, then your son or daughter get’s a free pass. Ditto with Mark Zuckerberg, John Paulson, Kenneth Griffin, Gerald Chan, etc. Like it or not, that’s the way the system works.
