I used this course to clean up my resume after working for 15 years as a freelancer on more than 10 project.
It was a useful exercise. My resume now looks more professional. The course is brief and to-the-point, with useful tips to improve. It is a very short course, max 1 hour per weekly module.
I only audited the course, did not pay for a certificate. So I cannot judge the value of the peer review exercise and resume review.
