When did you try to move up, JV and Varsity?

Hey everyone, new to the forum. Really enjoy reading everyone's thoughts and opinions.
Just got my certification last year in basketball. Question is when you were starting out when did you feel comfortable trying to offiiciate J.V. games. Or did you try to stay with JH games for a while.
Last year I was able to do multiple JH games and a good bit of youth travel leagues. I'm trying to get as much experience as possible before trying to move to Varsity in a couple of years. Thanks for the feedback.
