This course is designed with beginners in mind, and it is an excellent introduction to SQL. I intend to further my knowledge of SQL after taking this course. The instructor did a terrific job.

Great introductory to the SQL programming. This will definitely not only add another programming skill but also give me more capabilities programming in SAS. I would recommend this to anyone.

Course teaching was excellent, but the final assignment questions were terrible.

This is a basic SQL course. I'm not sure why it is called "SQL for Data Science" other than that is a catchy title. I took this course to refresh my SQL skills. It did give me an idea of where I am weak, but I don't feel I achieved my objective.

Quizzes poorly and ambiguously worded, database carelessly extracted

Three stars because (1) the lecturer is good, and (2) Despite the bad "user experience" provided by this course, I did achieve my goal which was to acquire a working knowledge of SQL. Some of the final project questions were confusing, or not well explained. Some of the answers given in the rubric are wrong (Part 1 question 6). Only a few mentors are present on the Forum and they often give incomplete answers to questions. One of the homework questions is incorrectly posed; this has been pointed out 6 months ago and is still not corrected. The student must waste a significant amount of time trying to understand ill-posed or confusing coding assignment questions. This level of neglect to improving the user experience is really *not acceptable* for a paid course.The course could be greatly improved by having someone with pedagogical as well as technical knowledge to address the task of rewriting and fixing the coding questions that many users have complained about.

This course is great at getting you started in SQL. The complexity of the assignments however exceed the practice questions available. Further there are not enough practice questions to become fluent in using the concepts described. Feedback: more practice questions.

The Assignment was mis worded and didn't reflect the content of the course

Clear instruction, but quite easy. Would prefer if it was more challenging.

Certain quiz questions were unclear. Final peer-review assignment had unclear/ambiguous questions that didn't fit with the data in my opinion. But content is useful. Delivery could be improved.

Good program for beginners. Peer review assignment needs to be updated. The assignment is not graded by instructor. Certification means nothing because anyone who pays money will eventually get it.

It was a great course and I've definitely improved my SQL skills, however there were a few things that could be improved. Practice questions and quizzes should be placed throughout the course material, not at the end just before the final quiz. Secondly, the content itself could be explained in better ways. Not always very clear.

No practice examples at all. Videos have only theorethical queries without results, so you can`t see how it works on practice. Reference to SteckOverFlow is awesome. Why should I pay money for nothing?

As can be seen in the discussion forum, the course is not really so well designed. I found some difficulties during the process even if I have learned programming before at intermediate level. The language sometimes is confusing. The lecture examples in the last two weeks weren't helpful in understanding the concept and improve coding, though the coding test is not hard to pass. The course has improved according to the discussion but won't be so helpful if you really want to get some solid skills in SQL. I came for this course for prerequisite and I actually studied at UC Davis before, so a little disappointing.

should have provided more explanation and help for exercises and assignment questions. The lecture is also not in depth enough.

This is a mostly a course intended to review, that's to say, you need to have prior knowledge of SQL if you want to make the most out of it. If you're just a beginner, I wouldn't recommend it though, there are a lot of things that remain unspoken and are important. Readings are okay, but in my humble opinion they fall short to what SQL world can really offer. This, I consider it mainly a sneak-peak.

Overall good course. The lectures could be made a bit interesting and engaging with exercises broken up. Found the lectures monotonous however course material is good.

The quality of the course decreased after Week 1. I understand what you put in is what you get out, but the course didn't offer any additional practice for the extra resources they provided. Also, the lectures were terrible as the instructor hardly showed any of the code's output, which means I had no idea if it was correct or not.

I think this course does not provide opportunity to learn sql practically. It only gives the theory of sql language, which I think is not sufficient to get the whole idea. Another thing, the quiz and questions are way too harder compared to the lectures provided.

The mistakes in the presentations and the massive ambiguity in the final assignment were a complete letdown for me. All in all, I did learn everything that was taught, but I wonder how much of that was made possible thanks to my previous experience in IT.

A little too easy, not challenging at all, given this is a beginner level class, I'll give it two stars. You could finish the whole course on Saturday if you get up early plus Sunday if you do not.

There are few examples about every lesson, and may not have examples for some lessons

The course gives basic elements of SQL, but there is no practice in the course (beside graded assignments), code is shown only in presentation (you cannot copy and and see how it works), and learning SQL without constant practice is nearly impossible. The peer graded assignment is messy.
