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.
Great course but could be better! I think the teacher should be more informational, and instructional in how to complete said tasks. I am currently taking the data wrangling course and that teacher walks through problems, and I think this course could benefit from doing the same. All in all a great course, but room to grow!

The course was informative and well- structured. However, I wish the course had more example problems in the lecture videos. I also wish the lecture sides showed the results of each query instead of just listing out the query. Overall, I feel like I had a good overview of SQL and some rudimentary knowledge on utilizing SQL.
By Blair L•
The course is easy to follow, well-explained and have enough hands-on to reinforce what we have learnt! However, the assignment and quizzes can be improved. Sometimes the contents of the quizzes are not covered by previous videos. Over all it is a good class for both beginners and people who want to refresh SQL concepts!
Not so difficult with previous limited knowledge of SQL. Videos could be better with actually showing the output of the code that were included. First time hearing someone say SQL as 'sequel'... or is this how it's actually pronounced? Instructor had a calm and soothing voice, although her body language was messed up.

I like the course, it was well done and exposed me to many of the key features needed to continue my SQL learning. The websites and other resources were extremely useful. The only wish there were more opportunities to practice SQL coding, maybe guidance to another site with questions, or more sample quizzes.
By Hannah M•
I found doing practice questions on other site helped contextualize the basics, but this course is definitely best suited for someone who is a self-starter. There are contexts and scenarios not covered in this course, and you have to seek out other problems and retrofit your understanding to do well in this course.

If the final assignment was not so ambiguous (many questions are misworded leading to wrong SQL codes, it is almost impossible to decipher what is being asked exactly) this course would have got 5 stars from me. Otherwise I liked the pace of the material other than maybe Week 1 and I enjoyed the coding quizzes.

Good course, learnt the basics of sql and some of it´s features. However, i think more excersises should be made, as it make you feel you didn´t train enough. Maybe one good option would be letting people hae acces to some databases, and then use a SQL program installed in the computer and work from there.
By Jeroni C S•
The course was great up until the final assignment which was very ambiguous. It was also a shame that they used such an old version of SQLite, where many functions are not available. However, I feel that it did fulfill the goal, which is to make their students be perfectly prepared for SQL in Data Science.

This course provided essential knowledge for using SQL in data analysis. The best part was the quizzes at the end of each module which enabled a complete practice of the concepts learned and the last exercise was very helpful to understand how SQL is deployed in solving real life data analysis problems.
By Sankalp B•
It was a very good course. A person with no prior knowledge of SQL can easily learn this course. I would like to suggest that for certain sections like joins, date-time, the course provider may consider introducing some animation into the lecture videos to illustrate how data is being linked/extracted.
By Mayur G•
The course is good but lacks proper explanation of queris and required some more illustrative way to show the handling of queries in videos.Requires proper graphics and additional programming interface to sshow and run the various queries discussed by the tutor in the videos for better understanding.
By UMESH S•
Expect peer review section this course was good. That peer review section confuses a person that how to do the task and what needs to submit. So in the place of this peer review include completed a problem data along with instruction and some hints and grade that as other assignments of this course.
By Rafael E•
The contents are very accessible and well done, as well the support tool for exercise is great!
However, you should consider to improve the final assignment questions. They are not clear and the database needs a code book with the metadata. It was tough to get the meaning of each field and tables.
By Marco S•
As introduction to SQL , I have found it very useful and well structered in order to get a better a grasp on the topic. The only thing I will improve is the part concerning self joins which by the examples shown in the videos I didn't get all. Maybe add more examples.
To sum up, very good course.
By Jim F•
Great place to start if you have absolutely no SQL experience. Videos are well paced and thorough. The final project could use some cleanup--as indicated by the forums full of people asking the same questions. I'd take another in the series if it started around the level of windowing functions.
By Mukhammad E•
How can i say about this course. Overall, course isn't bad, neutral. Tutor's pronunciation and English is so good and accurate and she always try to explain the course in detail. Disadvantage of this course, it is so theoretical and doesn't have many practical explaining during the lesson.
By Marko M•
Course gives very good info for beginners. I just wish there were more exercises between lessons. I felt overwhelmed by all the informations that I had to memorise before doing test at the end of each week. I think having more tests in between lessons would help me better memorise things.
By Yang G•
The course is very good for a sql starter to get to know the coding world. I would recommend any starter in our company to take this course. However the final assignment is a bit confusing and peer grading created a lot of stress... that's the only reason for the 4 score instead of 5...
By Elena K•
It was my first course in SQL and I liked it. In general, that's a good course with a lot of practice. Some things were tough and it would be better to cover them by more examples. Anyway, the course helped me to learn SQL and I'm going to explore the data world with my new knowledge.
By Catherine T•
I like the overall look, feel, and organization of the course. It was well paced and simple to understand. I struggled at times with coding questions as some are very ambiguous and there isn't always an easy way to find guidance in the forums. Overall, though, I was very pleased.
By Kausik D•
Overall a good course for the starters in SQL in Dtaa Science filed, however I felt it could be some more hands-on oriented with some more examples, and it was mainly of lecture contents, rather things could be shown visually for a better understanding. Thank You for the videos.
By Sabarish A•
Would have loved to see more live videos of how to do stuff. There could have also been an SQL initial setup tutorials in the system which would have been more beneficial on how to setup a relational database. But, I was able to learn the basics of SQL and how it works overall.
By Ivan K•
Buen curso que permite aprender SQL de forma rápida y eficaz cuando buscas mejorar tu CV y obtener habilidades necesarias para el sector de análisis de datos. La última prueba es un poco compleja...¡dedicale tiempo! No te copies de los github que puedas encontrar en la web ;-)

Very good course for beginners to start and specially for people without any programming background. The assignment provided at the end of every module give a very good exercise for practice. Only thing is some real life examples could also have been included in the lectures.
