Hey I'm a new instructor here on Udemy and I'm a bit confused on how the overall review system works. I have a new course uploaded and it had 7 -> 5 stars review and 1 that was 4.5 so my overall review score was 4.94 which was mathematically accurate to a certain degree Now someone left me a review of 3.5 and my overall review plummeted to 4.47 which is really weird. How are these overall review stars calculated? What would have happened if someone just left a 1 star review and forgot? my overall review for the course would have probably became 3.0. If someone has an answer please do let me know it feels frustrating and a bit unfair...
