I'm not looking to change schools or anything, but I have been kind of curious about this, because I drive 40 minutes to my class 3 times a week...What if you're like a green belt in TKD at a particular school, and you change to another school? What happens if they're with the same organization (WTF, ITF, ATA, whatever), what ahppens if they're with someone different, or if they're teaching style is a little different, then what? Start over? I'd really like to know what happens, if anyone knows, let me know ok? Thanks!
