You say key club and debate won’t get you anywhere, but neither will just a 35 or a 760 in Math 2 (just above 60th percentile) with that mindset.
I suggest you apply but think wisely - there are very many things that a typical 4-year graduate has accomplished or experienced that you will probably not - club leadership, advanced language classes, mathematics, and most importantly, for STEM, actual labs.
Learning a textbook and having an internal fact library is good, but not useful in college or really in the real world (this is my opinion so feel free to disagree).
Many schools (more so graduate schools) put taking a gap year in good light where you can grow, explore yourself, and put things to good use - of course taking a gap year isn’t for everyone.
I don’t particularly see a strong AP score in Economics, any math-related scores, objective science (like Bio, Chemistry, Physics) or even AP English Literature/Language. The scores you have are without a doubt good for the tests you took, but it takes more than that and “graduating early” isn’t necessarily a “wow” factor. You lack a lot of extracurricular experiences, what do you want to do? Did you involve yourself in a business club? Economics bowl? Did you intern somewhere? You will be compared to kids who took insane AP courses at full rigor in a public education system an hit the 36/1600/4.0 mark - but even that’s not the end-all since numbers can only get you so far.
But honestly, your responses are startling; nobody isn’t ambitious - we just temper our ambition with reality, reason, and our goals.
Being 16 and being 18 is very different - two years don’t seem like much, but your experiences, social life, social attitude, and ability to weigh the reality of life changes dramatically; you will mature.
I don’t think you know what “college” is.
It isn’t just a 4-year class where you get a degree and off to graduate school. It’s an experience that you cannot rush through or play in fast forward.
I am currently an 18-year-old taking a gap year, and to be honest, I would say I was very naive in retrospect.
As for taking college classes, that’s good, but don’t take too many - in fact, some schools will treat you as a transfer if you take a certain amount of college courses, and this makes it difficult to get into a “good” school however you define it.
Stats are also not everything - you can be as book smart as Albert Einstein, but if you don’t understand truly how everything flows or can’t socially participate, it will not only be difficult for you to fit in, but also find people able to relate to you - it’s simple psychology and at a teenage age, a year or two years difference is significant.
