Hi Michael, a featured review is an algorithmically chosen course review. You cannot choose it yourself. There are several requirements for featured reviews to display. These include:
- A course must have at least 5 eligible reviews for selection by our algorithm, in order for a Featured Review to display.
- Eligible reviews must have a rating of 4.5 or higher. In addition, the user leaving the review must have completed at least 20% of the course, and the review must be no more than 2 years old.
