Why do you think you will be “miserable” if you go to Scripps? If there is just one school on the list you are convinced you will be miserable at, try to have a calm and reasonable conversation with your parents about it and why you prefer other schools. But you haven’t given us any reason, you strike me as just not wanting your parents to have any say in the matter. Well that would be nice, but it is a huge amount of money and it happens to be their hard-earned money and a generous gift to you. There is a wide variety of schools on your list. Scripps seems like a fine option to me–certainly better than some of the others. The fact that you are even considering $250K+ in debt just to get your way with your parents makes me think that you have no idea about the financial realities of life. And no, you cannot borrow that kind of money, not even close.
“Thing is, he won’t tell me whether or not he’s paying for college until I graduate.” This makes no sense. Yes, he will be paying for college, because you cannot afford it, unless you have applied somewhere you will get a nearly full ride scholarship. If he doesn’t pay, you won’t enroll. If you don’t like his choices, you might like to investigate whether you could get enough money at University of Alabama and the other schools which give generous merit aid for high test scores. I am not sure whether your scores are high enough to get a decent scholarship from one of these schools or if it’s too late to apply now, but that info is readily available.
