I messed up my Junior year, do I still have hope for Ivies?

<p>Freshman and Sophomore year, I have received straight A's.
However when Junior year came, my grades began to fall apart. Never been so bad in my life. This is my first semester grade.</p>

<p>H Physics - B
H Jap - A
H Trig/Alg II - C
AP Chem - B
H US History- B
Art - A
H Brit Lit - B</p>

<p>My extra curricular activities are really great;
I am hoping my ACT score will be at least a 30.</p>

<p>HOWEVER, that C in math is really really killing me. I lost all my confidence in attending any of the Ivy leagues, because they even reject straight A students.</p>

<p>Even if I were to get straight A's with four AP's in SENIOR year, I am not sure if they will at all help. I just lost all hope.</p>

<p>My top choices are UC Berkeley, UCLA, Stanford, USC, NYU, and etc.</p>

<p>Please tell me if I do have any chances..</p>

<p>btw, my high school is a magnet school, ranked #2 in Chicago. Will that help at all???</p>
