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.

A little too easy, not challenging at all, given this is a beginner level class, I'll give it two stars. You could finish the whole course on Saturday if you get up early plus Sunday if you do not.
I wish that the instructor used examples that mirrored the type of questions in the coding exams. We did not cover all the material in the coding exam.

The structure and guidance provided on the final assignment was very poor, resulting in far more time required to complete than expected.
By Riccardo B•
too much theory, I needed something more 'pratical' that allowed me to start using and write code and not see a lot of slide with code

1.Very basic course.
2. Assignments level does not match with training level.
3. Need to provide class which includes query writing.

The teacher was not readily available to answer questions. The course was alright but I do not feel prepared to use my skills yet.
By Mathias M•
Very slow and badly organised start of the course with no to very little practice of how to use SQLite before the coding quiz.
By Seidler C•
The first exercises are still ok. But the final exam is really a mess. The questions are not as precise as they should be.
By Yash K•
Too much talking in videos with less examples. The exercises were vague and not enough information was given to solve them
By Bill P•
The videos had the wrong emphasis, and were far too long.
More time should have been devoted to the exercises/quizzes.

Not satisfied. There are better MOOCs for SQL/Data Science out there. I wouldn't recommend it for a SQL beginner.
By Bram M•
The course is good in itself, but answers circulate on the internet, making the certificate not very meaningful.
By Naomy A•
there is a lot of questions about how the questions were asked, i highly recommend you do see the discussions
By Neeli K•
Not enough examples were shared.
Certain concepts were explained without telling their underlying basics.
By Eslam R M A•
There are few examples about every lesson, and may not have examples for some lessons

The course is overall very high in quality and I found it really useful. The teacher explains the concepts really well and the exercises are very good. I really found joy doing the final course assignment. However, I feel that I got tricked into paying one more month of subscription, seconds after I paid for another month, I did receive the course certificate. I submitted the peer graded assignment one week ago. My plan was to continue with the other courses in this specialisation but after my experience with this subscription/payment philosophy, I will not discontinue and look for other online platforms with a better customer experience for me. Thank you nonetheless for the high quality of this course, I am certain many learners find the material extremely helpful, as did I.

Terrible and frustrating. My previous knowledge was literally zero, so I did learn something at the end,but the lectures are poor and non stimulating at all. Worst of all, the exercises are awful. Most of the time the task is not clear, there are no example to guide you and the material given in the lectures are most of the time totally useless. I felt very frustrated. Not a completely waste of time, but I would never recommend this course to anyone. I really wanted to learn something, but everything was against it. I speak to the creator of this class, seriously try to do this course pretending you are new to this topic. I will be clear it is very very very bad designed.

The first two weeks were easy to follow along with. Unfortunately after that the course was severely lacking. There were not good explanations of things and new things would be added in that hadn’t been covered. When you post questions the mentors aren’t much help and the students will try to answer if they can. There’s also no way to practice. I also would’ve found it nice to see the tables they were pulling their “examples” from. I had to use other resources to actually study and learn SQLite. I’m assuming the people who gave this course a high score are already familiar with SQLite and just wanted the certificate.

First thing the instructor said was this course is for beginners. I am a beginner so I signed up. There are so many references I did not understand, no step by step explanation of how to find the data required to pass the exams so ended up looking for answers on the forum. Only way I managed to get through the third week was because my husband new how to use python and he helped me find correct answers - which were different to the ones we were given.
New steps were brought in without any basic explanation, again an indication that prior knowledge is needed.
Awful and disheartening
By Jay P•
Pretty useless course, especially for someone looking to audit (learn for free). Well I would be livid if I actually paid for this.
Without a text editor in the course, you are trying to learn SQL via slideshow basically. There is no way to learn SQL without practicing. I switched to Codecademy's SQL course as it's much better because of the the text editor. They teach you and you practice with actual syntax and commands rather than stupid quiz questions. I still use some of the videos to better understand some concepts but only after I practice/learn them in Codecademy.
