Hey @Shantanukumar ,
1)You should share your course in your friend lists.
2)Make an Trailer or short videos about your course and upload it on YouTube, Facebook and Instagram.
3)If you have money to promote your course then I recommend you to promote your YouTube video,which you had created.
4)You should build a group of peoples, who are interested in learning this type of course ,so that you can share with them.
