<p>Since I know next to nothing about texan schools, I can only give out of state suggestions, but...definitely consider MIT. Obviously it's top in sciences and will give you lots of aid considering your situation. Many of the ivies would too, though they arent all strong in chem.</p>
<p>If you're female, try caltech- a reach certainly, but worth a shot.</p>
<p>A more matchy school might be carnegie mellon. Good luck!</p>
