First question has to be: are your parents happy to spend close to $300,000 for your undergraduate degree?
Second question: how important is marketing? b/c it’s not going to be a big part of the business degree at several of the places on your list. I don’t think Brown even has a marketing module in their brand-new business concentration, and pretty sure that there is only 1 module at Cornell Dyson.
Note that the UCs are not test optional and there is no financial aid for out of state or international students.
Most of your list is what looks (to me) like reasonable places for you to apply- but the stats on international students are brutal, so I wouldn’t pin hopes on any of them. Given your predicted A levels you should have some really good choices in the UK, and it’s hard to see where most of the schools on the list would offer you something that would be worth the wild disparity in price. A year exchange program would get you most of the benefits. But - if your parents are well enough off that they won’t notice the cost, and you have a hankering for adventure- go for it
You might, though, spend a little more time getting to know these colleges better- some of them are so different that they usually appeal to pretty different people.
