As a beginner, the course is easy to understand and follow, and the course teaches a lot of useful commands. However, I think the course still has a lot to imrove. Some codings in the lectures have problems (e.g. lack ','). When introducing new commands, the teacher did not show the running results of the coding example. I also think the course lacks some application in the real world. Maybe providing more real business cases will help students understand better about when some commands will be applied.

It is a very introductory course on SQL. I have never learn any SQL before and I can catch everything she said. People might find it extremely easy, but in learning programming you must make sure all the basics are well known to you before using them in more complex situations.

Excellent course in all basics of SQL.

Built-in sandbox is the most important plus of the course.

A lot of practice, a balanced number of lectures.

At the end of a good project that allows you to try out all the methods learned in the course.

Excellent.

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.

The Course was quiet good & descriptive, yet it didn't cover a lot of SQL such as how to use its platforms and how to connect to database, also, the differences between other platforms.

This was an amazing course. I learned so much practical and application skills from the course. The lectures are great, as our the assignments and tests.

Thank you for a great time!

Great course with lots of things to learn about SQL. Assignments were pretty challenging and the instructor explained the concepts nicely. A fantastic course to start with SQL.

Sadie St. Lawrence is a completely motivating person. Thank you, Sadie, for such an excellent combination of professional teaching and interesting tasks. Well-balanced course

Very clear and useful class! The outline of each module is easy to understand and follow, and the assignment is helpful to strengthen SQL skills.

Even though i have learned SQL from many sources but this is a complete package, felt completed after completing this course.

I loved this class. It was the perfect introduction to SQL coding. It was easy to follow and I learned a ton. -Rick

So helpful! Really helped me learn SQL on a level that I am confident enough to add it to my resume.

Good course. The peer assignments was a bit challenging hence most interesting as well.

Comparing to other stuffs, this is really brilliant

Very nicely communicated

The course was pretty good for a beginner. The instructor was very clear and explained all the concepts in a very easy to grasp manner. However, the entire course could do with more coding exercises. Concepts such as joins, group, etc could be better understood if there were more exercises. Also, during the coding exercise (at the end of the week) it would be really helpful if correct answer and an explanation would have been provided. Having said that, its really good for beginners and I would and have recommended this to others.

=) Very clear walkthrough of important concepts in SQL and why use certain functions for certain tasks.

=( Wish there were more practice questions so it's more interative.

=( Also it would be great if there are more "real-life" SQL practices that involve solving for an actual question that you might encounter as a data scientist working for a tech company.

Thanks so much for sharing this with us, Sadie!

Thought some of the intuitive thinking was a bit challenging, but really liked how the sqlite server was built into the course and didn't require any download or off-site work. Think some of the time estimates should be a bit longer, but overall good course.

Good course for anyone starting to learn SQL but the course needs more assignments to ensure that the learners have got a good understanding of the concepts. Also, the final project is a bit overwhelming to do without prior experience in SQL.

A nice course for introduction with SQL but they could have used the software currently used in the industry like oracle's MySQL or SQL server.

Would have been better if there was a chapter on connecting to an sql server from an application or gui.

Great course with great learning and an opportunity to apply that learning

While I did learn some useful bits, I found the course lacking. I think it could have been much improved if certain conditions would have been met:A. More practice! You don't learn a computer language by hearing about it, you learn by using it. The only practice this course had were the quizzes, and they were far from sufficient. I would expect each lesson to be followed by at least some practice. I often found myself venturing to different websites in order to practice what I had learned, and learned more from that than I did from the actual course.B. Better explanations. I found the explanations short and sometimes lacking. Moreover, at times there was no synchronization between what the instructor was saying and what was presented on screen (e.g. she was talking about products when the example presented data of employess). It's a small thing but can be very confusing. It is very important to be precise here. Again, I found myself reading elsewhere in order to better understand certain concepts, which I might as well have learned elsewhere altogether.C. Examples! Again, you don't learn a computer language by hearing about it. You learn by using it or by seeing how it is used. Whenever I'm taught something, I want to be shown examples of possible ways to use it. Examples were scarce and incomprehensive.D. Applicability. The course is called "SQL for Data Science", yet I found very little in the way of applying SQL to data science. I would expect a lot more tips and tricks and examples of real-life problems and how an actual data scientist would tackle them. There was almost none of that. There were positives as well. The instructor was pleasant, the course was pretty well structured and did provide an introduction (although not much more) to SQL. But I did not get what I was hoping for.
