I don't have enough extracurriculars?

As another poster said, it's about quality not quantity. If you know what you want to do with your future, find a way to be involved in that and work towards it. I'm a senior in high school and I'll be pursuing a music degree next year and I spent 7 1/2 years in band classes, taking lessons on one instrument, and now I'm picking up a second instrument. I got into my top choice music school within 2 weeks of applying. Find something you love doing and stick with it and spend a lot of time working on it. You'll be glad you did. I come from the same type of place you do. There isn't much to be offered when it comes to EC activities.
