Ok. From now on your skills will be determined by your exp.
The ruling exp will be gained from ruling tests/quiz (The first one is already over but a second one will be made shortly).
Now for the arenas. You can find a friend on WNA and challenge them (you make up rules, i.e. OCG only, TCG only etc.) If they agree, you will play 3 duels against him/her and make sure to take a screenshot at the end of each game to show who won and who lost.
Exp will be gained depends on if you won the match or lost the match
You will gain exp based on the exp of your opp.
You will not gain exp when you lose.

Opp has more than 20 exp than you:
