Women GB to USAG

[muvva]

Wondering if anyone has moved from the UK to US with their gymnast. Military family here and my daughter started gymnastics while stationed in England so has only ever competed NDP grades and metals. I'm wondering what the biggest differences are in terms of hours and fees. In terms of levels, it looks like Zinc is somewhat similar to level 4? Any advice would be greatly appreciated, I feel like I've JUST figured out the GB system and I hate not knowing things lol xx
