Very learning experience, I am a beginner in DS, but the instructors in this course simplified the contents that made me I could easily understand, tools and materials were very helpful to start with.
I thought this course introduced the topic of data science very well. I think I have a much better idea how to describe data science and common terms associated with the field (like machine learning).

The course content is exciting and high level. In this course the student does not do any hands on data science, except the occasional introduction to an IBM tool. Instead, they are introduced to a broad range of topic, tools, and perspectives on data science. It is a good introduction to the subject, and I would likely have given this course three stars, maybe four, had there not been so many large bugs, that at the time of this writing, almost two weeks since posting in the Discussion Forums and contacting Coursera Help several times, has not been fixed.
For anyone going into the course, please take screenshots of all quizzes and assignments you complete. If you experience the same issue I have, and hundreds of others are having, than your progress data may get erased. I should have received my badge for completing this course two weeks ago but it is still saying I have "overdue" items and that I've completed everything at the same time.
I am sad to give this one start rating, but so it goes. I hope they fix this as soon as possible, and it may end up affecting people's billing.

Has too rigid an understanding of a complicated field. The track would be better off without this class, as it's just confusing. Videos of "real people talking" are a big waste of time. Videos and material contradict themselves multiple times. Quizzes test memorization, and not actual understanding of the material (as in, only ST types will do well on MBTI typology spectrum, but SF, NF, NT that have better understanding will achieve worse grades, at least give challenging questions that apply knowledge learned, not just ask people to define terminology), peers literally copy paste answers for the final exam portion. Basically, just horrible and a waste of time all around, so at least make it just one hour.
Final project being in academic format is the worst, as data science projects in the real world are usually in the form of dashboards, presentations, or products... so this academia bs is literally useless in preparing people.

This course is overall very vague and too long. The whole content should be summarized in 3 pages of text. It is also a bit confusing. For example, it gives two different definitions of big data. There is also a whole paragraph about regression without defining what it actually means.
The risk is that this course gives the impression that anybody can become a data scientist, just by imagining some vague concepts and it will all be ok. The course could emphasize that data science is actually a science. It requires a tremendous amount of very detailed work, with some very difficult tasks.
This course would benefit from reducing the number of interviews and introducing data science concisely. Or, if the authors wanted to actually keep as much detail as there currently is, every concept should be defined properly.

A complete waste of anyone's time who knows anything about data science and would seek the data science specialization on this site. Further, the course material thus far appears to be a paid-for repackaging of free instructional materials offered by IBM at bigdatauniversity.com. Why I had to sit through this material is beyond me in the context of a data science skills tract. Please, stop wasting professionals' precious time and money with this material. This material took me merely a weekend to get through, not 3 weeks, the framing of which seems questionable at best. Please remove this from the overall specialization. My experiences thus far make me feel that I may not continue with this set of courses if this is the level of quality I can expect.

I am subscribed to and paying for the IBM Data Science Professional Certificate and when I attempt to submit a quiz within the "What is Data Science?" course the submit button displays "Upgrade to submit". When I attempt to go through any of the customer service or chat windows which themselves are hard to find, the chat window does not display properly or function in the slightest. This was also the case when I attempted to submit a support request or create a ticket within the mobile app. Terrible and frustrating experience. At this point I'm unsure as to what to do besides cancel my subscription and give up on the money I have already payed as they seem to be instant on not allowing you to contact any customer service representatives.

There should be an option to rate zero stars !
I am CS graduate, and also has deep understanding of learning algorithms. Isn't it's a huge waste of time, spending three weeks to recite the definition of data science and data scientist ? I believe most of the students in this course are somewhat from CS or equivalent background. And for them its just a trash!
People, maybe high school kids may say oh no its such a good course, i never knew data can be such impactful bla bla bla, they might find this course little bit useful than just googling : "what is data science ?"
And the quizzes, lol that's just joke. You have to recite salary figures from supplementary pdf so it might make you feel good! who knows !
By Olga L•
I am absolutely not happy with the course. The material is plain; the quality of videos is low; the concepts are mostly described by a robot with automated voice. Assignments rely on the fact that a student does not think on her own but finds the related phrase in the text and copies it. Peer reviews are unfair - I got a lower grade in spite of the fact my answer was in full accordance with the criteria, however was not a 100% copypaste, I dared to use my own words.
Really a pity - I was hoping to complete the specialization. Will probably search for something of better quality and fairer community.

Lost quizzes that I took multiple times, weeks after I'd completed the course and issued a certificate, Coursera web site now saying that I didn't complete it, and the certificate is missing. Many others have posted in Coursera forums reporting the same issue. We have reported to support and keep getting the same answer "our team is working on it". No timeline for resolution, no updates on progress. Nobody can complete the program and obtain the Data Science Professional certification if this class is not marked as complete.

This is not a course. I was upset when a subscription was renewed and I immediately cancelled. I tried to get a refund but coursera would not allow. You will learn more from youtube. This is a gross waste of time and money, and goes on to show how superficial our fixation on certificates are. The course is an insult. I could have taught the three weeks on an A4 paper, instead of watching some uninspired students.
Don't pay for this course, it's useless. For example: What's Data Science? It's what data scientists do. And at the exam you should have answered exactly like that, even if you don't have any idea on what's the meaning of "data". And this should be a "Professional" certificate. Try to answer like that to someone about whatever question you can think of and they will burn you alive.

The worst MOOC I have taken by far, the material being taught is all over place. For example, during the lesson on git command line prompt. The instructor was showing git commands BEFORE showing you how to actually linking the SSH and your github account to your computer. I read the review forums and it doesn't seem to get better, for python section either. Dropped the class.
By Filippo P•
The course is good but the support in case of issue is absent or very slow (at least).
When I try to repeat a quiz that I did not pass, the website just drag me again in the summary page in a kind of infinite loop.
How many days shall I wait prior I can re-do the quiz? I do not infinite time to study and now that I have the it I am stuck on a quiz that I can't repeat.

Useless BS Fluff class. Make some of this optional reading in another class, but don't make is seem like it has any value. You risk loosing people in different cert programs. It makes a cert program look inflated, such as 9 classes...with this being one of them it's really only eight classes. Then you start with this BS and you question the value of the entire program.
By Deleted A•
Too basic, useless and total waste of time and money. You get nothing out of this course except for some basic information about data science that you could have easily learned from various free online sources out there. I agree with other reviewers that the only purpose of this course is to drag out the certification process so that it costs you more money...
By Олимпиева Н В•
During this course, be prepared to wade through the huge paragraphs of the text. There are not so many practical exercises, just two, so most of the time you will play the game is true-false. The final assignment is not much about practising big data or data science technologies. I hope there will be increasing of the number of practical tasks.
By sandeep a•
waste of my money. Did not learn anything new, may be good for people coming from non-technical background. Video snippets without much technical value or learning isn't of much value to me.
The image recognition exercise is also not up to the mark in detecting parameters. I felt very disappointed and at loss with this course.

i was charged for this course without any prior notification mine money was deducted from mine account when I requested for refund there was proper channel to place query regarding refund. coursera is just a fake they take money in the name of education , it was mine life biggest mistake to come here
By Javier J•
This is really bad, I completed this course last month, and got the badge, no my grades disappeared, with not answer from teaching staff or coursera support, I'm not the only one.
I have to redo the course, due to the lack of support, I just want my professional certificate.
By Rudi G P W•
The quiz questions throughout the course seem to be asking the queston 'Have you studied?' instead of 'Did you learn the anything?'. This approach does not work well for me. I don't need to know the exact wording of a sentence to know if the meaning of it is correct.
By Rebecca B H•
This section of the course feels like a complete waste of time... Most people who have signed up for this program know what data science is and watching a bunch of random people give generic speeches about their opinion on it is boring and a waste of my time.
By Shruthi K•
There is nothing new I have learnt here., to know the definition of Data Science and its applications why would someone do a course of it, instead one can browse the definitions in Google search. It's just waste of money to invest in the course like this.
By SANKET P•
Not at all worth it.
Just provides insights to the field in layman terms without actually providing knowledge to a beginner.
All the lessons in the course are just interviews with people.
I do not recommend this course at all.
Would have rated it 0.5/5
Self serving plug by the author to promote his book and his thesis work. There are much better courses
Note to Coursera: The slides and videos are outdated. There are a number of forum posts calling for help.
Dismal experience. Worst course ever.

Google Simulating Environment has the bugs and when you writing to Support, this rich guys stat you to do a free "PROD" testing : no way, it's theirs bugs, and I have my own. What the hell are paid for?
Shame on YOU IBM for such solution!

My course progress was DELETED!!!!! I finished this a couple of weeks ago. Once i completed the third course in the progression for Data Science Professional it didnt send me my badge and erased the progress for the first course!!!!
