To be clear
Questions and cards in ViBJT are written by ViMai to follow the official structure for practice. They are not real exam questions, and the app is not endorsed by the Japan Kanji Aptitude Testing Foundation or Pearson VUE. Scores in the app are estimates. ViBJT does not guarantee any score.
FAQ
Is ViBJT free?
Yes, everything: 10 mock tests, 4,400 cards, audio and the guide. If the app helps you, you can support ViMai from the ViMai tab.
Do I need an account?

Which language is the app in?
The interface and explanations are in Vietnamese; the questions and cards are in Japanese.
Is the app's score the same as the real test?
It uses the same kind of approach (IRT, where harder questions count for more), but ViMai sets each question's difficulty. Treat it as a practice estimate.
Are these the real exam questions?
No. ViMai writes them to follow the official structure; no real question is copied.
