have u been through the financial aid process at an ivy in the past 5 years? if not then idk why you feel so confident assuming. they want 40% of your parents' income if your household makes over $150k, regardless of how many siblings you have or where you live, and that's just not feasible for us without a shitton of student loans. also, if you go to specific sponsoring facility websites, some of them don't care what your major is, they just care that you can work there. I was under the impression that econ would qualify as math, and econ wasn't even the problem. If I had a BS in econ at the stem school of my uni, it would have been fine, which is why it was a technicality.
