This course has really helped with optimizing queries that I work with everyday, enhancing my understanding of RDBMS, joins, analyzing and structuring exactly what you need and yielding those results.
best course for learning SQL for beginners.I learned so much from this course.the speaking language is also simple ..So i Recommended this course for beginners who's 2nd or third language is English.

You can learn this stuff on your own. You don't need a course.

Quite easy. The peer-reviewed assignment is also very easy.

These lectures seem incomplete. For several sections, I had to Google more information to understand the lecture topic.
This course is listed as a beginner level course with no prerequisite, but throughout the lessons I felt like I was missing some key basic information. The course recommendation is 20 hours, 3-5 hours a week. The first week fell into that parameter, but after that the hours required increased each week, with the last week being about twelve hours including the final project.
Ideally, this course considers adding in more complete explanations for the examples in the lectures (including outputs), more practice coding, and more depth on exploring data and making inferences from your queries.

Would not recommend. There's no real teaching, the instructor is just reading off of slides with little to no explanation. The slides are confusing, don't provide outputs to the codes that they're showing and many times have errors on them. The course including the quizzes forces you to do most of the work, and I mean that in a bad way. The videos are incredibly lazy and very little explanation is provided for some key points considering this is a beginner's course.
The only good thing I found was that it provided some structure to what I should study. I ended up studying mostly from tutorial websites. I would suggest you look for some other courses if you want to start SQL.

The lecturer is terrible. They read off of a teleprompter and the way the script is written is so unintuitive and verbose. What is the point in having a lecturer who's actually an expert on the topic, if they're just going to read a script like a robot?
The quizzes are good, but the topics covered in them are often not covered during the lectures. The lectures may go over the surface level of a topic, and show a really simple example but the quizzes are much more complex and will require you to find examples on the internet. The quizzes are the strong point in this course. The lectures are absolutely garbage.

Few suggestions for improvement:
1. provide a worksheet that summarizes all the material in a simple manner. It exists in many other sites so it shouldn't be a problem to provide this
2. In the quizzes and assignments - it would help to give a hand when the student does not understand the question or makes mistakes. to say "correct" or 'incorrect" is not enough.
3. the final exam is in no way align with the level of the classes.
and the worse thing is that in the forum it seems that a lot of students have complained but nothing has changed... therefore I would not recommend this course.

There are 3 major issues with this course: 1. the instructor appears to be reading from a teleprompter and constantly struggles with her text, making the lectures both distracting and soporific. The cheerleading ('Are you excited about joins yet?') doesn't do anything to change that. 2. Some portions of the final assignments are poorly worded and the mentors aren't active. 3. There is a huge backlog for assignment grading which is frustrating and causes the discussion threads to be polluted by students asking for others to grade their assignment.

This was a shockingly different approach to teaching a software language. I did not enjoy the style whatsoever, and found myself constantly seeking outside sources to understand what was glossed through. Unless you have a strong programming background, I would not recommend this particular class. Instead, seek something where you will complete SQL code yourself, with explanations of syntax, structure, and purpose, specific to the format you will be using. You'll do yourself a favor by doing so.

The instructor shows queries without showing the tables that are selected from nor the end result of the query. Often it is not clear what a query does by just watching the videos. Also you are not provided with the database that the instructor is using, so you can't rerun the queries and play around with them, which is essential for learning sql.
The questions during the videos and the module quizzes are too simple compared to the course material and the topics looked at.
Although the structure of the course is well organised the assignments and videos contain lots of mistakes. I had to spent a lot of time by searching in the internet what is wrong in my code to realise that the instructor code was wrong as well and should not work (although they provide the results as it works just fine). Moreover, some questions are written not clearly and the explanations in the videos lack advanced examples while talking a lot about unnecessary things.
