Is orchestra an extracurricular?

<p>I always thought that orchestra did not count as an extracurricular activity because, at least for my school, it is a class in which a grade is received, etc. However, I see many people including things like concertmaster in their activities when talking about their acceptances/rejections for ED. I forgot to mention that I am concertmaster for our school orchestra in the Activities section, so should I email the admission officers about this or should I leave it be? Also, I didn't write about my position as concertmaster in my essays, but I have talked about my experiences in violin.</p>

<p>Also, I listed the award I got in violin, but I didn't put violin as an activity as itself. Should I amend this as well? I have already submitted by apps.</p>

<p>yes it is. i put it down and talked about it in my short response</p>
