I noticed those randomly one day and did a few of them. I failed the one for the primary programming language I have worked in for the past decade and passed ones for two different languages I have hardly used and AWS, which I barely know anything about outside of EC2 and R53. I felt like there was a big difference in the quality of the questions and answers for each quiz. For the AWS one, for example, the phrasing used for most of the questions and answers made the correct answer basically obvious without actually knowing it to be correct.
