Didn't Kwak win Korean nationals if she is at the Olympics? I would think she would have had to win Korean nationals to make the Olympic team, I don't believe she was on the junior or senior GP curcuit.
Nope. Actually the winner was Kim Haejin, who is only 12 years old! (Same age as Yuna when she won her first Korean nationals). So she would be too young to go to either the Olympics or Worlds. (Heck, she might be too young to go to Junior worlds). The bronze medalist is also 12.
Also I believe Kwak was selected before Nationals anyway,
