What level extracurricular is iGeo?

I'm currently a rising sophomore, and I'm quite good at geogaphy. I think that I'm probably in the running for qualifying for the International Geography Olympiad (iGeo), which is the highest level geography competition that exists in the world, with 54 participating countries as of 2022. It is also one of the 12 major International Science Olympiads, although it's less prestigious than things like the International Math or Chemistry olympiad, and it probably isn't as prestigious as math or chemistry, since Geography is a rather niche subject. If I do qualify, I'll be one of 4 team members on Team USA. There are typically ~60 students yearly that participate in the qualification exam for the iGeo, called the US Geography Championships, in the Varsity division. What level would this competition be (from 4c-1a), and if I got a good score at iGeo (gold or silver medalist), would that make it higher than a level 1A?
