Hi @EmineYüceKa834, welcome to our community! We're glad to have you here.
As a start, I recommend checking our Marketplace Insights tool to check the availability and demand of the course you're planning to teach. Since your topic is in the medical area, I also recommend that you contact our Trust & Safety team at email@example.com before building your course to ensure the content will be eligible for publication.
If you have any questions, don't hesitate to reach out.
All the best!
