Link for quiz tool did not work and wasn't fixed after a month. The order of the units seemed like it made little sense in my opinion. Some questions were worded poorly or crucial information was left out or vague

I'm giving this one-star rating just because of no videos in weeks 4 and 5. Overall, the course is good but still need improvement in my English accent as it was hard for me to get it being an Asian.

I did not get much from the course. while the material is interesting but somehow some instructors lack the ability to explain things very clearly.

For many lessons the video lectures are missing. They have done the best they could with creating the puzzles. But all together very low quality.

some of the topics were fucking bad the explanations could have been a way more clearer felt bad

good content, but I have to say that is very and I mean very hard to understand the teachers

I'm not sure which is more bizarre, the topics being discussed or the quizzes.

solutions are contradictory. i am trying to unenroll, please help me, thanks

Too many errors and incongruencies. Often very unintelligible.

By far the worst Coursera course, I've taken
