I messed up my Academic History section on my UC application!

<p>So I submitted my UC app the same day I broke up with my boyfriend, bad move I know. I wasn't my attentive self and totally screwed up my 2014-2015 grades. I put all A's for senior year when I got a B in AP CALC AB-1.. I haven't even completed the year yet. I also left out that I did cross country my senior year in my activities section and left my non A-G courses section empty. How badly will this affect my chances at UCLA, UCSD, UCSC, and UCSB? I thought my chances at LA and SD were already severely low before the mistakes... I paid for all my apps so if I don't get into any of these schools, I'd be devastated. I applied to 2 CSU's as well as safety schools but I'm still afraid.

<p>I took a POSC120 course at a community college during 11th grade. I personally think my essays convey my story effectively and I got 100% on both of them in my AP Lit class. </p>

<p>I contacted the UC app support and they said that not much can be altered after submission. So apparently an attachment will sent with my app to the schools I applied to. It still looks pretty bad though. What are my chances? Thank you. </p>
