Hi @Allagani85 thank you for your question! Yes, you are welcome to publish preparation courses for exams such as Nebosh! Practice tests are designed to help students prepare for real certification exams and can be added as a lecture type to a course or be part of a Practice test-only course. You can learn more about them here.
You can also explore the topic’s demand and competition by visiting our Marketplace Insights tool which can also be found on your instructor dashboard under Tools.
For any specific questions related to the content you will be posting and the best practices on the platform, I recommend contacting our team at policy@udemy.com.
Hope that helps!
