Additional Info:
Ive only taken the SAT once and i never studied for it and i got a low score obviously (1500) in junior year. But currently im taking classes and studying and hopefully i can get higher than that. What minimum SAT Score should i hit to enter any of those colleges i listed? Also, as you can see my freshman/ soph year was pretty bad, because i didn't care about school and never tried. But later in Junior year , now i see how important is to go to college. I wrote good essays explaining my grades regarding my fresh/ soph year.
<em>Also</em>: Im in varsity soccer, cross country, and track. I attend a very good school in Texas that is ranked silver star in U.S. I am a minority (African American).
What do you guys think i need to do on my applications and essays to have a slight chance in any of those colleges listed.</p>
