I found at least one answer for 2 of the Questions on Quiz 2 was "close" to being correct, but actually all of the offered answers for these 2 Questions still contained some errors where they would not evaluate properly. I'm guessing that each person receives a set of different Questions on their Quiz 2 that they are confronted with; the Questions being extracted at random from a Pool of Test Questions (a New Wolfram Language Function: RandomQuestion[10]??).
Anyway, I'm not particularly bothered, as I passed it anyway, but would like to describe the particulars so as to contribute to an improvement in the Pool of Questions. For obvious reasons, I realize it might be best not to discuss this openly in this forum.
Is there an email that I can send the 2 Questions, and what I believe is incorrect as to the offered answers?
Also, it is suggested -in the Quiz- that to get the Certificate, you must get 60% score...I'm thinking that what is meant is the the score should be 60% or greater, otherwise I would have had to go back and change 4 of my answers to reduce my score back to 60%?
Overall, it's been Fun so Far. And I do appreciate the effort that the Gang at Wolfram has made in offering this course.
