I don't know if it was UC Davis team, or Coursera's team that was tasked with setting up the quizzes and assessments, but they were set up horribly. Please change this, some of the answer's in your auto-marker assessments are just plain wrong. It took me way longer than it should have, due to unnecessary complications by the course, and I cannot bring myself to do more courses from this specialisation. I hope other courses are better, as this was my first one through Coursera.

The quizzes are fine, but the copy is terrible. The instructor isn't very clear in explaining what the steps she describes are used for, and often just repeats the first half of her sentence. It feels like the writing for the class was rushed. Also, the instructions for the final assignment and lab aren't very clear. I was able to learn the basics of SQL thanks to this class, but I relied on multiple outside sources and tutorials to do so.

Didn't like it. Too simple content (could only bear it with speed>1.5). Too many errors in the videos. Peer review is stupid b/c the tasks were simple but time consuming. Some of the works I had to review were simply copies from the internet (I can tell b/c some solutions you can find on the web contain answers to questions which have been removed). Teacher, however, did a good job. Clear, easy to understand explanations.

This has been a very frustrating experience with Coursera and with this course specifically. I have been unable to access any repositories associated with the course so I can learn from either through the terminal (lab) or through visual studio. I am restricted from contacting the professor and none of the limited documents give any instruction for the assignments. I am very disappointed at Coursera.

The course does go through the relevant topics. But the assignments and moderator attention (and quality of responses) are well below standards compared to other coursera courses. I would not recommend paying for this course, but rather just audit it. This way you will still get the material, but you won't have to go through the really bad and frustrating assignments (unclear/ambiguous/wrong wording).

Videos are not helpful. Going over the concepts with some codes and hypothetical examples are not useful. It would be great if we see the codes run and some of the results. Also, explanations are inadequate. The notions are oversimplified and rushed through. I learned the topics by doing the assignments which are very good for self-learning but mostly not covered in the videos.

This class does not go into enough detail. The lectures are not particularly helpful. The final assignment is mislabeled in terms of time it will take which leads to poor time management. Some of the questions are also considerably more difficult and require skills not taught or practiced well enough during the class. I wish I had done a different class.

Worst MOOC I fell across on web. Lot's of bugs in the assessment, lot's of incompleteness, teacher does not go deep in subjects, ends with a peer review letting you no guarantee it will ever be review, certainly not within the Free Week. I feel like I lost a lot's more time then I should have for the content I learned, overall very frustrating experience.

It's so hard, not enough examples to refer to when doing quiz. You should provide a variety of examples prior, similar to what you will ask in the quizzes. For someone like me, new to coding, it's very hard to remember how to respond to similar questions by the examples. People need to get familiar with the examples first, then move on to something new.

To be honest, i don't think this is for beginners.

Many things you need to find our for yourself and as per today, i don't know which tool to use for doing the queries? How to make the tool go and take the data for the spread sheets? This is basic.. so now i know the queries but i don't know where to use it.... Did i miss something?

I honestly am very disappointed with this course, no live coding in action just lectures and slides.

I shall stick to Udemy and Data camp as they show the instructors writing the code live as they teach it in some editor such as MYSQL or PostgreSQL.

Instructor is great at explaining but no live video showing them writing the code.

Interesting course, it made me remember some things I learnt in college. Final assignment is too bad, simple queries for getting the info we are being asked to look, repetitive code to be implemented, a lot of ambiguity in the description of some points. I would call this course "SQL for newbies", or "First approach to SQL".

The course compared to other data science or programming classes I took was not effective in demonstrating how to use in a practical way the foundation of sql. No files were provided for exercises, exercises and lecture were read, no documents or link to install sql lite were provided. This is not a professional class.

Many errors in video and the quizes: the course has never been corrected and will never be, admins doesn't answer on te forum section. The videolections are useless since you can't apply the examples that are being explained and you don't even rhave the dataset necessary to understand the examples

I do not like this course. I could not even get through the first week of this program. All the instructor is doing is talking through 'her ideas of using SQL' not actually indicating how to perform the actions of doing SQL. I get a much better, interactive experience through LinkedIn Learning.

This course was not hands-on enough. In my opinion, we should have been practicing each of the techniques as we learned them. Watching a bunch of videos completely misses the mark. It was also difficult to do the assignments without the practical experience.

Won't say a bad instructor but this course is surely not for a beginner. What she is doing, is just telling what happens if we use this and that. No practical examples. She is not even defining the technical terminologies. Bad experience

Not enough in-course practice and they do not teach you how to install/use SQLite in your computer. I guess this course allows you to speak thoroughly about SQL more than it teaches how to use in real-world scenarios. Needs to improve.

The course wastes a lot of time in going over "learning objectives" in each video. There is so much redundancy that the entire first two weeks can be condensed into 1 hour of actual material. I felt that there was a lot of time wasted

really going to unsusbcribe from coursera because of this course, Python for everybody was really good, but what the hell is this SQL, the teacher sucks, she just literailly reading her notes instead of teaching. Worst teacher ever!!!

Class work should be similar to the Final Assignment to cultivate thinking. Also, Solutions should be provided so that we can learn from mistakes. Coding for week4 has errors, this should be tested and fixed.

This course is very difficult the instructors do not give you any real example and, in each Coding Quizz you have to struggle in your own to approve.

They should check the content and add more real exercises.

This is a nice introduction to SQL

But, it had almost nothing about Data Science

The final exercise is graded by "classmates" usually a bad sign. This final exercise was very tedious and needs a lot of work

Many mistakes in the exercises. Content is so-so, at times it's too easy and at other times it skips over important subjects very quickly. Final assignment very unclear and the data set used is incomplete.

i don't recommend to take or purchase this course as it have some wrong information which force you to answer the quiz wrong to pass it. also the instructor sound to be not professional in teaching SQL.
