At age 7-8, mine successfully went from Xcel Bronze (Bronze bars routine was: glide, pullover, back-hip-circle, under-swing dismount -- which I think is pretty much the L1 routine?) to JO L4. Vault was tough all season (low to mid 8's), but everything else was fine and she even medaled at state on beam (3rd place), bars (5th place) and AA (7th place, I think). My kiddo is definitely not a gymnastics super star.... so if she was able to make a similar jump then it is definitely possible (assuming your coaches would even allow it). Just make sure your DD is OK walking away from meets without medals clanging around her neck -- there were many meets, especially at the start of the season, where mine ended up with just one medal.
