Help! Ec's

<p>Right now my only EC's are Wrestling, Track, Math Club (including AMC contests and such), Outreach (like a service club but you design your own project), and I've been playing piano for 12 years (the problem with this is that I slacked off big time for like 8 of those years so in my experience and age group everyone is way better, so I don't have any competitions or awards). Wrestling consumes most of my time so other EC's like speech and scholastic bowl are out of the question, and pretty much everything else at my school is bs. I want to try to get into really good tech schools, and most everything else is solid on my app to give me a fighting chance, except for my EC's. What are some EC's I can do, preferably by myself or not at school, that will help with that?</p>
