It doesn’t matter what anyone else in your class got; all that matters is whether your Selection Index is above the threshold for the whole state.
This is a very significant thing to determine, in your situation. Your parents’ assets will make some “full need met” schools unaffordable with need-based aid, depending on that particular school’s formula. (As already stated, you really need to run the NPC projections for all schools you are considering, as a first filter, but even that may be less accurate because of the real estate situation.) If you are NMSF, you will have some good full-ride options that won’t be affected by need calculations. For example, U of Tulsa, which treats its many National Merit Scholars very well, and has both accounting and finance undergrad majors in its business school.
