hii i hv created course and about to publish just want to know that is it possible to edit course after publishing ? Can we add more videos after that to make course longer
yes you can add videos to make your course longer after course is approved and published.
Please be sure you publish something complete enough to grow for a few months. Since the course duration is one of the factors students might be enrolling, the additional content will push their time for completion making some anxious ones leave a low rating. So one possible approach could be to publish a beginner level course first, get some feedback and then either add more content to make it intermediate/ all levels worthy or just go back to drawing board and publish a new course from scratch with the additional content pivoted based on learnings from this one. Don't treat it like a playlist on YouTube that has built-in expectation of growing incrementally overtime. A course is more like a one-shot release and annual update as needed style. Multiple approaches possible with no silver bullet solutions so plan accordingly. Many older posts in forums have discussed these things in past, worth a scan.
Yes, absolutely.
