I am of the opinion that it is wonderful to enter college ‘undeclared’ so that you can explore and find your passion before declaring a major. You clearly haven’t identified your academic passion yet (even though you are a capable coder, for example) but this is fine…it’s great.
Many American colleges embrace this. Many of the Ivies, many top research universities, and probably most liberal arts colleges don’t require you to declare a major until maybe start of junior year. I think you should focus on these schools. I think Stanford is in this camp.
As you probably know, other universities DO require you to apply to the college of arts or sciences or engineering or social sciences, etc etc. If you’re not sure where your academic passion is yet, then I don’t think those schools are right for you.
‘Business’ is broad, and successful entrepreneurs, managers, marketers, and CEOs come from a wide range of disciplines. The best engineering manager I ever worked for was a Forestry major (and he became CEO of a tech Fortune 500 company).
So my advice is to relax about major, and focus on schools that look like they’d give you a vibrant academic experience. You can always go to business school later.
