Magic the Gathering!

Judges I’ve met seem to have these tips in common for people wanting to become Judges:

Think about why a particular rule is in place.
When going through the Comp Rules, ~~strike~~ what you believe you already know. Helps gain more time for the things you don’t know.
Use your resources and network. Ask other Judges.
Get out there and judge! You don’t have to be an official Judge to judge at low key events like FNMs and such.
Take the practice tests. Remember, in the questions the active player’s name starts with an “A” and the inactive player’s name starts with an “N”!
