Chances for Rice University?

<p>I have made a bit of a shift from being completely academic, to a balance of academics and extracurriculars.
I am ranked 4 in my class of 400, with 8 AP classes to date.
SAT: M 740, CR 730, W 750
Extracurriculars:
Academic Decathlon (State Qualifier)(9 Region Awards), NHS VP, SHS VP, Student Council President, Beta Club President, Interact Project Director, Academic Quiz Bowl Captain.</p>

<p>What are my chances of being admitted to Rice, or similar schools, like Washington, Vanderbilt, Emory?
What about for Merit Scholarships?
How can I improve? </p>

<p>I'm sure this post would be helpful to those with similar statistics looking at these schools.</p>
