As I'm sure you all know, the laws of our wonderful games, together with the variations, signals, trials and clarifications can be found on the World Rugby website at...
https://www.world.rugby/the-game/laws/home
But did you also know that there is a laws training module available
https://passport.world.rugby/laws-of-the-game/laws-of-the-game-exam/
You should all complete this laws exam at least once a season. You can't actually fail; if you get something wrong it just takes you back yo the relevant section to reread the law.
