Chances for DUKE, Rice, UT Austin, or Baylor

<p>I am actually only a sophomore right now. I have a 3.75 GPA. I got a B in geometry PAP which kind of dropped my gpa a little. I am at least in the top 30 students in my class. I am currently in students council and math club. but i will also soon be joing NHS and SHS. I am taking all advanced classes. I am even taking Spanish 4 AP this year. currently i have a 98 in World History AP. So far am i on the right track? If it helps i live in Texas and the 3/4 colleges i want to go to are in Texas. I have a PSAT next week so what score should i aim for at least?</p>
