Adjustments have been made to make it easier to see cards when multiple cards are moved to the Graveyard or Banished Zone at the same time.

-Master Duel Proficiency Test:
The new mode has two parts: a knowledge-based quiz-style section and a practical section that will test your actual Dueling skills. When you clear both sections, you pass the test, and your grade will increase.
Academic Exam: Random quizzes will be assigned with their difficulty depending on grade. A certain number of correct answers is required to clear each test.
Practical exam: You will clear the section once all of the Clear Conditions have been met in Event Duels and/or Ranked Duels.
