If your parents won’t pay and you’re on your own, then you don’t have a choice. Gone are the days when a student could self fund through a part time job and a loan. (Do your parents know how much college costs these days? By the time you’re enrolled, it should be between 35 and 70k a year…)
Scholarships aren’t common. There are full tuition scholarships (and some full rides). Are your parents willing to pay for test prep - and which kind (Advantage? Private tutor?)
Howard has full rides, for example. Check out the criteria for full rides at UAlabama, UAB, UAH, Auburn. Look into U South Carolina’s Honors Program and its perks, Pitt and its scholarships. Essentially, start looking at colleges with strong honors programs and scholarships.
However, full rides and even full tuition scholarships are not common - over 99.5% don’t get one. What will happen if you don’t get such a scholarship? Will your parents assume you won’t be going to college?
Just living at home and commuting somewhere costs money. In fact, they should at a bare minimum be willing to pay the same for college as they would for you to live at home - they may have other priorities than your education, but they can’t expect the college to pay that for which they’d pay if you were living at home, right?
