So, if you want to modify the content, just wait for the review to end (whether it is approved or not), you can edit the course content again.

You need to be an instructor before you can open a course. To become an instructor, please register as a general member before applying to become an instructor.

There are three parts to the preparation process before the class, which are 

1. What will the students learn after the course? 
2. The prior knowledge that students should have. 
3. Who is suitable for this course, which is where the instructor will clearly describe the targeted group who is suitable for the course.  

The more detailed the description of the target audience, the easier it is to attract students to join. It will also highlight the instructor’s major and understand the needs of students, so please fill in carefully."
