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.

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

i want my money back

=) 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!

The Content of the course is good, quizzes are fine, but the final project is a total mess up, inconsistent and don't contain the course potential, so you won't be able to apply the knowledge by doing it

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.

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.

Great course!

Interesting content delivery carried out in logical sequence.

Perfect course! But recommend the last main exercise do more readable and understandable. It is difficult to read in a text file, single-color task and it is not always clear what needs to be done.

very hel

This course is structured very well. Used concepts widely used in Data Science/Engineers work.

Few concepts required more details.

Excellent way to continue to develop SQL and Data Analyst skills

Excellent course structure. Thorough lectures and examples. Working with a real database from Yelp was very useful and made the course work enjoyable.

very good

very very good course

I took this course due to a new project at work which involves checking the input data by querying it using SQL scripts. This course has really eased my job. It covers the basic stuff pretty thoroughly. I recommend this course to anyone who's just starting out (or aspiring) to be a Data Scientist.

Great Information/Presentation.

It wii be better if the website can provide some description for each variable in the ER diagram

Great for beginners -- helped me realize I'm not a beginner anymore.

Straightforward and easy to understand. Great course

An excelent course. Complete and understandable

This course provides me the basic techniques to jump into the electronic medical records and start to code queries and provides reports to Clinical and Research Management. The test are intense and the final project is a real challenge. The good news is I learned to code as a beginner SQL programmer.

This was a really good course! It was comprehensive and thorough. Truly truly great course!
