Some quiz is too hard.

No sample for playing on network and XR.

Now that I took the Unity Certification Exam, I can say that the questions provided throughout this course ad infinitely easier than the questions on the exam, which led me to expect a much easier exam than it really was and cosequentelly taking it without being well prepared for it (which was supposed to be the objective of this preparation course).

If the questions were ill suited for the purpose, the lessons provided were really even worse, I think I had lost more time trying to replicate what the instructor wanted, but really leaned very little by doing so!

I'm sorry but I couldn't recommend this course to anyone. Since there are such good tutorial material online, it is a shame that paid course, sponsored by unity, is in many ways inferior.

Very disappointed, despite having had 98.5%, 100%, 100% and 100% as my Coursera courseware grade!

Course content is good, but is full of bugs. When taking the quiz's, if you submit it won't show you the answers you choose, it only says right or wrong. Making it difficult to learn from your mistakes. Also it won't show you the reference material to learn the answer to the question, like in the other courses in this certification. Lastly the way that the peer review assignments are set up you most likely will have to wait for some time to receive a grade, I had finished everything else and was charged another month of the course because I was waiting for someone to review my assignment, which was graded after their predicted completion time. For a course that is $79 per month, you would think someone would go through and make sure everything worked correctly.
