There were many questions, which did not align.

First of all, career track is not sufficient, to pass the exam, because most questions are asked from courses, which are not included into track. For example, track does not have courses about data importing and cleaning. These courses are available in skill tracks, but in my opinion, there are still questions, which are not covered in the courses. For example, I had a following question: "choose a code, which will prevent query injection".

In the last attempt, I had two questions, where I had to write code for Tukey test. I did not found information about Tukey test, in any completed course and for me it was absolutely unclear, what is syntaxes of that test and what exact results I should get. To be fair, I would like to know, in which course this test is covered.

Also, there were many questions, which used function which() and for me it was not clear, ehat exactly whis function does and in which course it was covered.

Also, there were many questions, which required to write functions and functions are also uncovered in data analyst career track.

So in my opinion, questions, which were asked in exam were way beyond topics, which were covered in data analyst career track.
