In other words, a perfectly normal HS junior.
The saying goes that the biggest major for incoming college students is: “Undecided”.
And even among those who enter with a major, a large percentage will switch majors by the second year of college - so they just didn’t realize/admit that they too had been “Undecided”.
Once people take courses in college, and hear about fields of studies by their peers, they often find themselves attracted to a completely different field than they would have ever imagined - or even heard about in high school. This happens all the time - and this might be your path, a perfectly normal and expected path.
In fact, maybe because you are able to excel in many areas, it might be particularly difficult to discern which topic or two to concentrate on, without having more in-person experiences at university.
Yes, large universities, or most liberal arts colleges, that will happily welcome the “honestly undecided” students ought to be a good home for you.
