I am about to start my first year of college in the fall at a non-arts centered school, so my experience here is severely limited, but I'd recommend applying for all the weird scholarships you can. I have a friend who just looked up a scholarship a week and applied to all of them and she turned out pretty well.
I will warn you, however, that though SVA is an amazing school, it is a for-profit school (actually the reason I didn't decide to apply there), which might mean that they won't be super generous with scholarships. Outside scholarships would be the way to go in my opinion.
Good luck!! I hope that you can find a good way to pay for your education though and I hope that you have a ton of fun and learn lots!
