Advice please

<p>hmm..I'm new at this.
Well, I'm currently a sophmore.
I took two math classes in freshman year, and I didn't do so well in grades. I had a high A average in the first semester, but in the second semester, I did horrible. Low B's and even a C!!!!!! (ouch...i know)
I was wondering if I get high A's for the rest of high school and work hard(which I'm doing successfully now), if I had a chance in some good colleges. (recommendations! please!)</p>

<p>some things about me:
Secretary/treasurer of INTERACT

Active member of the teen advisory board of local library

participated in duke tip program</p>
