Can I modify the exam content after the exam has been published?

It is divided into the following two situations:

1. For exams that have already had students participating, you cannot increase or decrease the number of questions. However, you can modify the question content and correct answers. You cannot add options to multiple - choice questions or blanks to fill - in - the - blank questions.

2. For exams that no students have participated in yet, you can click [More] - [Stop], then add questions. After completion, simply publish the exam again.
