Question re: EC's and UC admissions

<p>New to this, so I thought might seek some helpful insight from others. I was wondering how heavily weighted EC's are for the UC admission process. Is this make or break?</p>

<p>Our daughter is NOT looking at UCLA or UCB - she would like UCSD, UCSB, UC Davis, or UC Irvine. She is a junior, just got SAT results of 1440 CR/M, 2100 overall. GPA last year was 3.83 unweighted, this year so far is 3.57 unweighted, 4.0 weighted, should wind up slightly better after 2nd semester is counted. She has taken AP and dual enrollment classes, and is in top 10% of her class. </p>

<p>We thought this all seemed great and pretty much in line, but having started looking on CC and reading info about EC's for others, now wondering just how big a part this will be in admissions. Would welcome any knowledge! Thanks.</p>

<p>Well, update one year later! Accepted to UCSB, UC Davis, waitlisted for UCSD and UCI. Daughter is vey happy and we are very proud. </p>
