How much can EC's help?

<p>Just like I said above. What about Colleges such as the UC's that do not put so much emphasis on the UC's. Will the UC's see a SAT score 100 points lower than their standard and the applicant with an average of 3.5 gpa for example instead of the UC's standard of 3.7 UW average, then throw it out? Will a list of EC's with a couple larger ones such as starting a club or being part of a major program as band/sports get the student in over someone who had a 3.7 UW and the average SAT for that school with much lower EC's? Thanks.</p>
