grades vs ec

Which Ivy league school(s) is/are more focused on grades rather than ecs? Because my ecs are pretty bad-sophmore right now.

Also what are some things to do to improve your ecs besides starting a club or attaining a high position (president, vp, etc)

<p>You can always improve EC's by doing community service, joining things you like to do and staying committed to them. I'm pretty sure Cornell looks at EC's less than the other ivies (they have accepted people at my school based mostly on their SAT/GPA/Essays).</p>
