Any Suggestions?

<p>Hi!
I am a sophomore in high school and I was wondering if there was anything I can do now that will improve my chances of getting into TCU. I have a 4.22 weighted gpa and a 3.73 unweighted. In the past two years I have completed 7 honors courses. I am on drill team and take 3 dance classes a week. I teach a dance class each week as well. I am in the 80th percentile on the PSAT's. This summer I am volunteering at a christian camp for special needs children as a junior counselor. Does anybody have anything they regret not doing in high school? Is there any way for me to boost my credentials? Also if I could get into TCU, how hard is it to get scholarships?
Thanks!
