Hi @DamanDevSood, great question!
The course can indeed be held in an unpublished state, officially known as 'Need fixes', if the Review team identifies any areas that can be improved or need to be corrected in the course. The course will get published once these updates are completed.

Let me know if you have any other questions! 🙂
