I'm very disappointed of the quizzes even there's no solution or model answers to follow to know our drops !! I tried too many time to solve the quizzes and nothing happened except for Retake !

I will not continue this course unfortunately !

Hello

to all how works in this course thank you

It is a great course!

excellent

My course 3/4 in this specialization is still incomplete because the questions had wrong answers in the module quizzes and it was literally taking HOURS to complete the quizzes because you had to guess which one of the wrong answers would be correct this time. The questions rotate through slightly different questions each attempt so you can't simply use elimination on each attempt, YOU GUESS EVERY SINGLE TIME. IT'S LITERALLY 100% LUCK! I thought maybe course 4/4 would be better but nope, same problems here. I've wasted over 6 hours in total trying to pass these broken tests and I'm completely over it. I also reached out to chat support, they went through and said they couldn't find anything wrong and couldn't help me and a refund was impossible because it's past the refund date. Even though I paid for 2 broken, un-proofread, time wasting courses. Also, in course 4/4, the math tables in the videos are staggered all over the place and looks terrible. Seriously an issue of someone not even looking at the video before publishing, would have taken less than 5 mins to fix for the entire course. Also, every time a "checkpoint" question is supposed to pop up, nothing happens. In every single video, they're all missing. I've used Coursera for a few other courses and thought they were reliable but this makes me think otherwise and I feel like such an idiot for paying $200 for this COMPLETE GARBAGE. Other people in the forums have shown they have the same problem posted over a month ago but nothing. Please, someone from Coursera get a hold of me and help me resolve this ridiculous problem.
