Not sure if the marshmallow test is valid any longer:

But in any case, as others have noted, OP you seem to really, really want to go to the unnamed LAC and really really don’t want to go to UT. Since I don’t know which LAC is involved, will only mention, again, that UT has a great reputation, and has been pointed out, has clout in unexpected areas(IB, see above).
But if you are absolutely convinced that the LAC in question is the school for you, then that’s that. My question-and I’ll admit I’m confused after reading all the posts-as how you will fund it, who signs what loans, and who will be the loan originator. When that much debt is involved, keep in mind you are making a decision not just for today, but for 10 years from now.
