Yea we never get into the concept of who around her are in what level. Rithik and abbie have been in level 1 and level 1/2 for like 3-4 years and this is their first year going into a full on level 2 class
I just checked their history and this dancer literally just joined in April. TBH knowing that I wouldn't even do this whole process of asking the teachers and x, y, z. I'd give them the feedback and that Ken didn't flag her as being in the wrong level or needing to move up and that, again, the class will progressively grow more challenging throughout the year. Her spending at least one full season in a level 1 class is fully acceptable and normal.
