Looking to become a judge

[Leviathan]

So I have been curious about this for a while and have the opportunity to do some floor work as a judge for a local event. What I am asking is there any advice that would be helpful, anything I need to know, and where do I go from there?

Thanks for any and all help!

I'd say start by taking the online test to be a Rules Advisor, as I did. It's easy to sign up for and they have practice tests.

Once you have that, you'll have access to other helpful resources too. It's a good first step before Lvl 1.
