Hi @DrNehaSharma, did you do some research on Udemy to find out if there are similar courses already? Is there maybe even a lot of competition? If not, think about who would buy your course? What would they search for? If there is not much competition for the keywords you use, I think it's a great opportunity to create a course.
If you find similar courses, read the comments that students leave. They tell you a lot about what they expect, also what they didn't like. So when you create your course, make sure that you cover the stuff they didn't like in other courses. This will give you a competitive edge!
