Not so much a chance, but more like how much will it negatively affect me?

<p>So here is my dilemna:
I'm applying to Chemical Engineering at UC Berkeley. I'm in-state, and I have a good weighted GPA, 2290 SAT, 770 math 2 SAT, still need to take SAT Physics. Only problem is that I had two B's in Calc AB last year. Calc AB is a really hard class at my school, which is otherwise not super competitive, and I'm in the top ten (not percentile, but top ten students) when it comes to weighted GPAs. I believe I have unique extracurriculars, with a focus in science, and decent community service leadership, and a strong interest in the humanities. I can't judge how my essays will be, so overall, how much do you think I am negatively impacted by the two B's. Also, if it makes a difference, I went to a competitive research program over the summer (not naming for privacy, but it has a 10 percent acceptance rate, is well respected, and many of its participants go to top colleges like harvard, yale, stanford, and competitive BS/MD programs). To make up for the 2 B's in calc ab, should I focus on making my essays very science-centered to show how passionate I am about getting in? Thanks! Also, another question, I have inconsistent extracurriculars, should I still include them? For example, I volunteered for 20 hours at a certain place, but could only do it for one year b/c my parents refused to take me anymore? </p>

<p>BUMP! </p>

<p>Should probably bump it when more people are online…</p>
