Just to echo what others have said, level IV was a true litmus test for the gymnasts at my DD's gym this past year, out of the 10 girls in level IV, only 3 progressed to V, 1 repeated (my dd), 4 moved to excel (to do gymnastics for "fun"), and 2 quit completely. So 60% drop out of JO rate. The girls all liked each other and the coaches, no drama with the gym, the season was hard but fun, the team won a couple of trophies, the better girls won medals, but it is a huge wake up call where a lot of the girls just feel like they are at their limit with what they can do where in II and III the skills are less challenging and there is a lot more optimism with what they can do someday.
