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.
A comprehensive course that covers major aspects of query building and retrieval in a management system. The topics were delivered well and the materials/assignments were relevant for skill-building.

The topics are well explained but the videos are monotonus (slides and the teacher talking). I think the course could be more interactive.
By Serena G•
Good for learning basics of SQL but not much application and integration of concepts. In general, however, it is good for beginners.
By Kalide E•
Course would be much better if you can work alongside the instructor. Using presentation slides in a coding class is not ideal imo.
By Мамедбаков И Р•
The lecturer maybe is a good data scientist but does not have the skills of presenting or explaining material in an easy manner.
By Chan J J•
should have provided more explanation and help for exercises and assignment questions. The lecture is also not in depth enough.
By Chen K•
Course schedule was good , but content is a little short. To make improvement, should present some example during the video
By Thais S B•
This is a good course for basic knowledge of SQL but the quizzes and assignments are very confusing and badly elaborated.
By Mohsin K•
This is a good course on SQL for Data Science. As you will particularly start from scratch and go uptil tedious methods
By Dhwanil V•
The overall format was quite good but it would be more helpful if more examples are included in the lecture videos.
By TSUBASA T•
This course is helpful for beginners, but I felt that some explanation weren't clear and quizzes were challenging
By Saswata B•
More explanation of concepts is required. Also it would have been better if SQL code was explained in depth.
By Smit P•
Instructor should have explain each code by performing practically on pc instead of showing only image.
By Nick J•
not really relevant to 'data science' its more of a general basic introduction to CRUD and joins
By Ayush K J•
examples for important concepts were lacking like the use of GROUP BY and CASE statements
By Christopher M•
Course teaching was excellent, but the final assignment questions were terrible.

Clear instruction, but quite easy. Would prefer if it was more challenging.
By Islam M S M•
The Assignment was mis worded and didn't reflect the content of the course
By Tessa S•
Nice course to get an introduction to SQL. Not so much practice material.
By Abdullah F•
Just teaches SQL. Nothing is taught about how its used for data science
By Simone D•
The course material seemed prepared in a rush, with several mistakes.
By Greg L•
Quizzes poorly and ambiguously worded, database carelessly extracted
By David A•
It could be harder with some excersice that make the student search
By Daniel E•
Good content but the questions are badly worded and need updating.
By Melissa V•
Need to take a more in-depth class to fully understand this class.
By Matt E•
You can learn this stuff on your own. You don't need a course.
