ECs over grades?

My academics are not up to par with many other candidates being accepted to prestigeous schools, however I have a lot of leadership/extracurriculars - will they give my application any more weight and make up for the poor academics? Here are my stats:

Weighted GPA: 4.2
Unweighted GPA: 3.7
Class rank 30/300 (however, the school is highly competitive, blue ribbon, distinguished, voted 95th in the nation by newsweek)
School size 1,500 (4 yr public HS)
SAT 1800 (equivilent to a 1200, will definitely raise)
ACT - awaiting scores
4 years track (2 varsity letter, 2 team captain)
Usual club memberships (CSF, NHS, etc.)
Eagle Scout (senior patrol leader)
ASB Class Officer (member of executive board)
Certified Personal Trainer
4 years staff manager at private training gym (avg 15 hours/week during school year, 20-25 hours/week during non-school year)
Black Belt (member of demonstration team, instructor of youth classes)
Total of 6 AP’s and 3 honors (by end of senior year)

I will definitely improve my SAT to around 2000 in June (I took it once and bombed) - let me know what you think, thanks

<p>Your EC"s are good. But unless they are spectacular in one area in particular, they are not going to make up for you mediocre grades and test scores if you plan on getting into schools like Ivy Leagues, Stanford, berkeley, and the rest of the big shots. But hey, don't let me discourage you. Stranger things have happened</p>

<p>ECs are more for smaller colleges while stats are more for bigger universities.</p>

<p>If he bumped up the SATs, he'd be ivy league cailber...cornell definitely</p>
