Very sad to be writing this review as I was looking forward to this course after completing the first offering in this specialization. This course isn't for me. I completely understand that datasets may change over time, but someone must update course content so that the examples on screen match what students are doing at home. I really liked Kat because she is obviously wicked-smart and presents well. But I have a hard time paying for training that seems to be somewhat haphazard in organization. Just my 0.02. I'm out. Good luck to all...

~BEB~

This course is part 2, but it is expected that you know much, really much more than you learn in course 1.

In addition, a lot of exercises are very badly explained, on the final exam, 4 of my 4 peers I had to grade, could not submit their work, due to the use of a very badly explained software where you had to create a report.

It is also expected that you know how web-sites and events work, for me this was the biggest challenge, due to not have a background in this industry.

A lot of stuff you need to do, is not explained!

I've started 'Learn SQL Basics for Data Science Specialization' and am about finished with the second course. To be honest, this specialisation is poorly planned; the second course does not correspond with the first, some topics (such as PARTITION, AND-WHERE inside subquery, etc.) are not discussed at all, and Mode Analytics frequently stops operating due to its 10Mb limit. Let's have a look at how the UC Devis teach Tableau. As for SQL, they definitely failed.

this course/module is vague, the instructor needs to revise the course and deliver the content in more efficient way. the instructor herself sometimes made so many mistakes. the dataset is difficult to understand, and she can tell her story with a more understandable dataset. understanding the steps for retrieving the results is totally a chaos for the learner. please either remove this course from the certificate or update it in a more proper manner.

Very poor organization, there's no explanation of how to improve the coding, the guides about how to use the programming tool are not updated to the current look. A lot of students are lost, posted questions and nobody answered them. It seems I am my own teacher here, everything was about comparing your code with the code they provided. I understood, I just have to programm myself things and tests them, better to learn by myself.

Terrible, chaotic teaching style! This is the first time encountering such a poor instructor in my entire life and I have a master's degree in engineering. I am unenrolling. Cannot believe this is an instructor who was nominated for outstanding instructor! Must be "a trophy for all" kind. Would have given 0 stars if possible. Btw, absolutely loved Sadie St Lawrence's course in same specialization.

This is a really bad course. Its my third data analytics course with Coursera, the first two were great. The presentations are good, but the phrasing of the questions is so vague I wasn't what I was even supposed to do for many of the first two units' practices. Then when I went to watch the solution videos many of them end mid sentence before we even get the full solution.

I dropped this course on week3. After week 1 the presentation and explanation of the material became very frustrating. The instructor has a good grasp of the subject. However, the material and its presentation to the students were not polished at all. One could do better investing time on other free tutorials. I do not recommend this course, it is not worth the $$

very poor structure. solutions not provided in an accessible or usable way. no flow between this course and the prerequisite. the 'practice exercises' often cannot be completed without viewing the solution due to a total lack of actual question to be addressed and no guidance for what you are expected to be learning. total waste of time and money

Awful explanation, with mistakes and many gaps compared to the first course in this Specialization, this course made me feel like I had no idea about the fundamentals of SQL, simply because I could not grasp any basic fundamental knowledge in this course

The worst course I've ever taken here. I left it as impossible because it is difficult to follow, without a clear structure, and the translation is even worse. I'd rather learn anywhere else, I don't care about the certificate, I want to learn SQL well.

I don't like it, The metodology is a bit confusing; I realized at middle of the course that i need to save the SQL queries in order to use latter, so, should be mandatory and will be usefull to advertise it at the beginning of the course.

This is probably the worst course i have ever taken on coursera. It is paced horribly, has no natural progression from the previous course and there is generally no structure or actual teaching in the the material. Skip this if you can.

I do not recommend this course. The dataset has been updated and does not match the instructors. I also feel that this course is a big jump from the first one. There really isn't much teaching. I will not be completeing this course.

Code in lectures not explained properly. Discussion prompts with questions asked - these questions were not covered extensively beforehand. There are videos of solutions afterwards- but these discussion prompts seemed pointless.

Poorly designed course. Exercise are not good, instructions are unclear.

Wasted so much time to figure out what to do next, how to do it with unclear instructions.

Covered important concepts but couldn't practice them through

Not able to understand anything. Have to go through videos multiple times to understand what the lecturer is saying. No references, just talking and nothing else - worst course I have taken.

I am withdrawing from this course. The firs section was great with Sadie. The second, data wrangling, is very difficult to follow, feels very unorganized and without direction.

Very bad course. It's worst than the first one. The teacher intonation is not clear, just like she's humming by herself. The video they made sometimes are not updated

I don't think materials provided, especially for the installation of mode were correct.

I had to search how to use it on my own which took a long time.

bad teaching, you just see someone trying to improvise answers, its slow, some correct answers for test are in fact incorrect. Not recommended

Not very explanatory, it seems that is not taking into account the fact that most of the students are beginners.

Work on the assignments, define the question and more important point out exactly what's been asking for.

The instructor is really bad

Didn't explain the concepts and solutions of the questions efficiently

Very boring course. Not very well explained. Bad examples

I learn a lot more in a course on UDEMY
