What do I need to do to get into an ivy league school?

Ivy league schools only accept the top of the top of high school graduates. Almost all of their students have unweighted GPAs above a 3.8 or something like that, and if you didn't do well your freshman and sophomore year, you basically have no chance of getting into any of them.
Just go to the local university, you'll be saving money on applications (each application is like 75 bucks per Ivy league school) and tuition. You can do a lot with a STEM degree from a local university.

your chances are very slim, and thats just in general not just for you. it heavily depends on your GPA grades etc and I would say its highly crusial you take the SATs, that's how they determine how smart you actually are bc grades and GPA arent enough. it will look good that you have a business and outside work.

Like the other guy said you dont have great odds. Best bet is to go to a school that wont milk every penny out of you, and then possibly if u wanted to try apply for graduate school at an ivy. good luck man

I'm an athletic recruit at one of the top Ivies. Unless you're recruited, have a parent or sibling in the faculty, or are famous I wouldn't get your hopes up. Once you get through those three groups, there aren't many spots left even for legacies, let alone normal people. It's still worth applying, but if you can do well at another solid uni, then you'll do be in basically the same spot as if you went Ivy.

Also, take the SAT/ACT/foreign equivalent. They literally won't even look at you without it.

Professor writing here.

First of all, think "elite schools" not "Ivy League". The Ivies differ significantly in quality and prestige (It is, after all, just a football league), and there are quite a few other universities equal to or better than some Ivies.

Second, elite schools ARE open to nontraditional roads to entry, and yours - screwing up high school but getting your act together later - is one they are particularly fond of.

So it is not impossible. It would have been nice if you had done well in those business courses, to prove yourself academically. So it would be wise to take some CC classes while you continue to work, and to actually show up, do the work and get some decent grades.

but WHY do you want to go to college. You give the very strong impression of not being at home in the academic environment, and you are well on the way to a successful professional career without it.
