Very challenging, yet that's what make it's rewarding. Even though the course only takes 3 weeks, its difficulty is on par with the longer previous course. I enjoyed every problems on it!

More in class projects similar to final assignment where we can challenge our knowledge as we are all remote and it takes time to communicate through the available coursera forums.
Thank you.

This is definitely the worst IBM course I have taken. Truly awful. The good: It introduces you to multiple visualization packages, albeit briefly. The instructor responses to most of my questions were detailed and helpful, though many responses I saw to other questions were unhelpful or even inaccurate. The bad: Where to begin? The course suffers from very poorly written/designed instructional materials. For example, students are often tasked with creating visualizations that don’t make much sense or are not optimal for the situation. The final project material is particularly awful. The dataset students are given is a synthesized dataset that is very poorly designed. Even the instructors are not sure exactly what the rows and some of the variables represent. Of course, creating a visualization using a dataset with a nonsensical structure is likely to produce a nonsensical result, but sometimes even the visualization prompts themselves are nonsense. Why were we asked to create a bar chart with two continuous variables and one categorical variable? Why were we asked to create a line chart for data that has multiple observations for specific x-axis values? Students complained about this, and the staff said they would fix it months ago but have not, which is another issue. You might often find yourself thinking “what abomination of a graph did I just create? Is this right?” then checking the solution code and seeing that you are correct, it is just a nonsense plot. I would be embarrassed to show somebody the work I created in this course, even though I did it correctly. Many of the quiz/exam questions and/or answers are either vague, nonsensical, or not very educational. As an example, a question on the final exam (which I will not write here) asked a question akin to asking “What feature of a car is helpful for buying a car?” What kind of a question is that? Students complained and the staff said they would remove it months ago but have not. Another question was like asking “What kind of animal is a dog?” and giving the answer choices: A) A furry animal B) An animal that hisses C) A lizard D) A dead animal What is that supposed to teach us? What do you mean by “kind”? The course materials are also full of typos. Did nobody proofread the course content and think critically about it? Some responses I saw from instructors also contained many serious typos. Also, as previously mentioned twice, errors and egregiously badly written course material are slow to get fixed (if at all?). I wasted so much time wondering if I was doing something right, if something was a typo, or what a vague prompt or question meant. The course materials also use deprecated functions, sending me on a hunt to find and learn the current functions. None of this is helped by the script-reading robot voice that often lacks subtle but important intonation and sentence pacing. Another, more foundational issue with the course is that it doesn’t really teach you that much about each visualization package. This is especially true for the dashboarding section. There is no way I would feel confident building a real dashboard for an organization with just the knowledge learned in this course. The lack of depth is also exacerbated by the fact that the visualizations being created are not well suited to the problem at hand or are based on nonsense data. If this course is meant to teach us useful skills, shouldn’t we be creating realistic visualizations that are representative of how a data analyst would visualize real-world problems? I could say more, but the bottom line is that I do not recommend this course for learning data visualization with Python. I seriously hope IBM overhauls this course.

Coursera:
The hands-on lab portion of the Coursera course "Data Visualization with Python" cannot be accessed for more than two weeks. Several students have posted their concerns, and they have not been answered."
On accessing the Skill Network through the site and clicking I am not a robot the screen appears that says "Please wait while we prepare to start your lab environment. This shouldn't take more than a minute." The connection either times out, or posts a gateway error more than 90% of time." I have tried on several networks, browsers and computers.
Attempts to bring this to Coursera Learning Services, led to the following email exchange:
From Coursera:
Thank you for contacting us and bringing this information to my attention.
I understand how important are your Learning goals and I'm truly sorry to know about the whole situation. The good news here is that you can Rate a course or course materials.
When you rate a course or course materials, the instructor will see your feedback. You won't usually get a reply to your comments, but if the instructor wants to follow up, you'll get an email notification to the email address you use for your Coursera account.
To rate a course:
Log into coursera.org to see a list of courses you’re taking.
Find the course you want to rate.
Above the course title, select the three-dot menu and click Rate Course to open the rating window.
In the rating window, rate the class by clicking one of the five stars.
You can also write an optional review of the course, but you won't get a direct reply.
Click Submit.
To change your rating or to send more feedback, repeat the steps above.
This is the easiest way to alert IBM about this inconvenience in the platform. I hope you find this information helpful. Please feel free to let me know if you have further questions.
Kind regards,

My Response:
Dear Coursera Learning Services,
This is an entirely unhelpful answer. My contractual relationship is with Coursera; you should manage your vendors.
Moreover, I have directly contacted the instructor, and despite their quick response, the problem remains unresolved.
I will file the report, because I sense that Coursera has no interest in advocating for their customers. I implore to advocate for your customers with your vendor to get this resolved.

CAN SOMEONE TAKE OWNERSHIP OF RESOLVING THIS? PLEASE!

I have 2 professional Python certifications and have been programming for 3 years, but have little experience with the libraries covered in this course - this is an incredibly poor way to learn the subject matter even if you have familiarity with Python itself. Concepts are very poorly explained (sometimes even incorrect). Instructions and wording on quizzes, projects, and plugins are unclear and even nonsensical at times. The code in plugins and the final project is practically written for you - they are essentially fill-in-the-blank questions and do not measure your understanding of the material. The cloud IDE environment is extremely buggy, and even when it's not, the code they provide to set it up may not even be correct and will throw errors. For every hour spent in the course, you will spend 2 more seeking other sources. At the end of this, I do not feel confident in my ability to use Python visualization libraries despite getting an A in the course and being certified in the Python language itself, and will have to seek out an actual learning resource for this topic. This course is just an extremely frustrating required step in getting that little "IBM Data Analyst Certification" line on your resume. It is good for little else.

This course lacks of explanations. Theory is very badly built. It was clearly the worst that I have done so far. I only learn about the "existence" of some tools or posibilities but it is imposible to understand how those works.
As I said theory clarifies nothing and as for the practice exercices would only for advanced students who already know the tools and need to practice to remember again.
The final assigment reflects the lack of foundation wich is consistent in the whole course. But the worst is that you have to do a master just to post the answers. You have to really do a collage of images, cut paste... really artistic. It takes more time posting the answers than really doing the assignement. At the end you would be graded not only for the accomplish of the final assignement but for your skill in fitting different screen shots in one image. Very sad.
Lastly, it is very disappointing to see that students have been complaining for those things since 2019 and they haven't done anything about it. That is ignominious!
