Bút Nghiên helps teachers create exams and run tests on the web, while students join classes with a code and take exams on a server clock.
- Create exams, import questions from text-based Word, Excel or PDF files, and save them to question banks with topic tags.
- Exam blueprints, question and answer shuffling, and Word export with multiple paper codes and an answer key.
- Assign exams to classes with a join code; answers are saved automatically, even on a spotty connection.
- Automatic grading of multiple-choice questions, rubric-based essay grading, and difficulty and discrimination analysis.
- Students review the questions they got wrong in the Mistakes notebook when the exam allows viewing answers.
