If it were me, and I was planning to apply to an Ivy as a transfer student, I would take the effort to look up each Ivy I was interested in and see the actual application requirements for transfer students.
A friend of my D’s complained in HS because she said her guidance counselor gave her the wrong application deadline to a school she planned to apply to, and she missed the deadline. I don’t know if the guidance counselor made a mistake or if she was just blaming him for her own mistake, but to me there are times you don’t want to rely on the possible mis-information of others.
