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.

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 !

Quizzes containing wrong answers - Videos not showing tables correctly - Course not maintained in years - Hands off

Good pace of introducing concepts which made the course learner-friendly.

The order of numbers shown in video presentation are incorrect.

A great and concise course with great information!

Hello

Top Class Course and best faculty

Excellent content and structure

It is a great course!

Good Course

excellent

There are many problems with this course:

1- There is a lacking quality control. In many lessons the team wouldn't trouble to make a presentation were the numbers were aligned. That's too obvious to miss and to simple to correct. The fact that it was not done give me the impression that the class was done without the proper care.

2- In some videos the teacher says the same thing in sequence, which means no one bothered to edit the material.

3- The quantitative quizzes are more of a guessing experience than a learning experience, since you do not have proper feedback when you make some mistake some answers are clearly wrong as many have informed in the forums for years now and no one bothered to correct it.

Don't wast your time and money here, you will only get frustrated.

I expected a lot more in terms of quality from a course linked to the University of Illinois.

Need better feedback when taking quizzes on incorrect answers, including what is the correct answer and why.

Peer review is not a great way to score something. For example, I reviewed several assignments and found them lacking - basically the work did not follow directions, was obviously done without any effort or was incomplete. I followed the instructions and provided a thoughtful submission, and someone gave me a zero, and now it is unclear whether I have to take the whole class, even though my overall grade was over 90%

The reason why I have given 2 stars is because the week 2 quantitative analysis of this course does not have fixed answers. Yes questions change but then sometimes even when questions are same with same numbers and same wordings, answers change.

very difficult and quizzes and assignments were not proper

explanation and tests are on different planets
