What a colossal waste of time and money. I took the course specialization of 3D printing and Fusion 360. The course is so outdated. The curriculum was written in 2015. Many of the links no longer work and some are no longer accurate. One of the apps you need to download for the course was discontinued in 2017. I wasted 2 weeks doing assignments and watching videos that taught nothing. There was a specific module I wanted to get to, so I kept wasting time to until I got there. Once I got there, I found it too was outdated and extremely vague. Assignments are peer reviewed. Some of the assignments require uploading a link of the completed assignment. Once submitted, those links turn to text only and lose their hyperlink. Coursera doesn't allow copying from text, so you can't copy the link into your browser. So, you and your peers cannot review the assignment. How do you review an assignment then you ask? You don't. You give your peer the benefit of the doubt and give them a passing grade. I can keep going, but I think you get the point. Don't waste your time or money with coursera. There are far better resources out there.
