The DEX-450日本語 exam includes 60–85 questions and allows 105–120. Before test day, divide the available time by the number of questions in a timed practice set to establish a steady per-question pace. If a difficult item starts consuming too much time, mark it for review and move forward instead of losing momentum. A full timed practice session can help you decide when to move on, when to return, and how much buffer to reserve for a final check.

The passing score for DEX-450日本語 is 65%–80%, and the official exam fee is $200 USD.
