You can choose the number of questions and the order they appear, and review only the questions you got wrong. ■ Your Very Own Study Partner Customize the character’s name, image, and dialogue. You can set what they say when you start, when you get an answer right, when you get an answer wrong, and when the test ends. The closing line can be adjusted based on your accuracy rate. ■ Create Questions from Study Materials Import study materials from your camera or photo library; you can rotate and crop them, or ask the AI to generate questions. After generation, review the content and select which questions to save. ■ Organize with Flashcards and Folders Create flashcards for each learning topic and organize them into folders.
