Purdue, Illinois and Michigan…flagships are terrific, but very costly for OOS students.
What schools DID you apply to? It’s possible that, for engineering, you already have some good choices. So??
Your other threads indicate you are applying to some Ivies…and had questions about aid at MIT and Stanford.
And you have financial issues in that your dad gets a tuition benefit at your private school that is considered compensation.
So…where did you apply…because your other threads indicate all very highly competitive, expensive reach schools. Can’t imagine that those public universities you mention upstream are more competitive.
Also, don’t you live outside the U.S? That being the case…ALL public universities will be at the OOS rate…unless there is some reason why you would qualify for instate someplace.
