The course structure is quite upto the mark and the lecturer Miss Sadie explains all the concept in an interesting way. There are 2 scope of improvements I suggest for this course:

-Using MySQL instead of SQLite because SQLite isn't used much in the industry

-Including Windows Function in this course itself instead of the other course ahead.

I had issues with week 3. I think the outputs should have been included with the code during the videos so the examples would be more helpful. The forums were very disorganized. I commented on a post and asked a question but didn't receive help on either. Overall, I was happy with the class and am looking forward to the next one.

This course gives a really good introduction to SQL, no pre-knowledge needed and it feels like the level reached at completion of the course is very satisfying for a 4-weeks program.

The final assignment is a bit confusing and could be improved, but the lecture videos and practice quiz at the end of each module are very well done.

Liked the lessons a lot, the examns and the assignment is slightly more complicated to the queries shown on the videos though. The level of exercises shown in the video lessons should be higher so students know what to expect from the exams and assignment. Aside from that, explanations are clear and the course is very enjoyable.

Great material and videos. However, the questions on the final are ambiguous and can be very challenging, and the final as a whole can take much longer than the anticipated 2 hours. On the other hand, if you can make it through the final, you will come out with a great introductory understanding of SQL by the end of the course.

I enjoyed the course and definitely know and understand SQL statements now. In the future, it would be helpful to provide additional tips on where to practice your SQL statements to help those of us who need that extra help.

The instructor was very clear in the videos which made it easy to follow. Thanks for a great course!

Aside from stumbling over words, and clear video cuts, I think the course was effective, however there could be improvements but showing more examples during video demonstrations and more detailed explanations. Some parts of the course tells you to do something without properly explaining or demonstrating the WHY behind it.

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.

I learned a lot but I needed a lot of extra tutoring from my husband to really grasp some of this stuff. There needs to be more examples shown of data, SQL and output, not just SQL. And there needs to be more practice of basic queries to really get the foundation down. I feel like I was scraping the surface of the basics.

G​reat course but will require focus, and dedication. Course teaches to its best ability but leaves out a few concepts that could be driven deeper like LIMIT, distribution, and few others. Overall great course but little difficult! Use outside resources to your advantage during this course to help grasp the information.

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!

It was decent, covered a lot of questions I had about SQL (such as JOINS, performance difference between JOINs and SubQueries, etc) and encourages you to read further into the topics via external sources. However, there are parts that are very misleading, such as Views being only temporary, which is not always the case.

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.

This course was very informative! It covered all the basics and used real-world scenarios in the practice sections. My only resommendation is to find a way to practice each subject right after you learn it, instead of learning a group of subjects and then trying to recall everything you learned for the practice quiz.

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.

Thanks,

I​ would have loved more hands-on examples of how to use certain queries. In many occasions, I was forced to look up some concepts on YouTube to get a grasp of how it actually works and what results to expect instead of just a basic definition of what it does. However, it was a great and enjoyable course all along!

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.

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.

It is not one of those too much detailed courses and for some stuff you will need to look them up in a different source. And it lacks coding and testing in the lessons. Maybe with lab sessions it would be better. On the good side exercises are great and they make you learn the most things in this course.

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.

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.

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.
