This is a written test – it will not be available online. It will evaluate your knowledge of Problem Solving Card Text and Advanced Game Mechanics. Study materials for PSCT and Advanced Game Mechanics can be found on www.yugioh-card.com.
The test will first be available at the NAWCQ. Further information about where to take the test afterwards and its regulations have not been posted yet.
And no, you probably won’t get a Nyarla mat out of this.
