I have made a course and I have set it to free so that I can get more students so when i set it to paid one kindly help me out on this. I will be thankfull
Careful with that.
I think one of the best ways to get your initial reviews is to head to Facebook or Reddit and help a related group with their problems. Once you gain trust, let them know that you have a course that may help. Don't advertise right away as you'll just most likely get banned and blocked from the group or subreddit.
