No, I wasn't in the ATA. I stopped because I was really busy with other things. I'm also in the marching band, and about a million clubs, I tutor, and do volunteer work at the local library, and I've been taking all Honors/AP classes since Freshmen Year... so it was just too busy for me to continue. I only got to my first degree black belt before I stopped, I got it when I was 12. My little sister still does it though, and she's going to be testing for her second degree later this year.
