Your best of looking at state schools like UTA, UTD etc. I would highly recommend that you don't apply to out of state public schools and only apply to privates with need blind admissions and need based financial aid. It's just many places like the UCs don't give very good financial aid. People I know personally have less family income and still didn't get enough financial aid to go to UCLA/UCB (and I am instate which means it costs 30 thousand compared to the out of state 54 thousand)
Your SATs and GPA put you near the bottom for most higher level schools. That being said, you are still significantly above national average. If you can improve your SAT score to 2000+ then you have a significantly better chance at getting in places. Privates are probably your best bet just because they are going to be able to offer the most financial aid. Maybe you should check out some like Occidental or around that level.
This all being said, considering the financial situation you stated, you do pretty well for yourself and most admissions officers will respect that a lot.
Also, 1 thing you should know, you don't apply to business school right out of HS. You go off to regular college and get a bachelors (probably in econ, management, or acct. of some sort) and then after that you go off to business school which requires more standardized testing and more apps. A lot of the time for business school, they don't want you to go on and get an MBA right after college. You'll usually work for a few companies from a period ranging anywhere between 3 and 10 years. After that, you'll go to business school and get an MBA.
Anyways, Good luck!
Chance me back? New SAT Score! Chance a rising Senior! Will chance back
