I second rooting for Tulane.
but the reason we insist on your talking with your parents is that, each Spring, there are heartbroken students who come and post on this website because their parents had not discussed finances with them and they now find - too late to apply anywhere else - that their only choices are unaffordable, or that they have to go to community college or take a gap year, or that their parents wanted them to attend a specific school all along…
If you really can’t bring it up, apply to a “financial safety” where you can go if other plans fall through. There’s still time to apply to many universities so make sure you either talk with your parents and get a “sure” number or find a financial safety.
You shouldn’t plan to get more in debt than the federal limit, ie., $5,500 for freshman year and $27,000 total.
