Very demanding course, but it is quite a rewarding experience.

It is the best course I've taken so far.

It's an amazing course. The final assignment is quite challenging but fun. All in all a very rewarding and satisfying course.

Worth it !

Cool as Hell!!!

I found the first 4 weeks of the course amazing: just really well structured, thought-out, and delivered in a way that positions the student for success. Jana breaks the material down into digestible bits, gives you sufficient practice, and even if you don't get it, you can look at the answers to the practice questions and figure out where your thinking was incorrect.

The 5th week wasn't as well broken down, especially the last set of Teradata exercises. New concepts or ways of structuring queries were being introduced in those exercises, but there was no way to check for a correct solution if I couldn't come with one on my own (which was unfortunately half of the time). I still got a good grade on my last quiz, but I can't say that I really truly learned how to write the more complicated queries.

I would suggest that the last Teradata exercise set has more explanation or perhaps just answers that the student can refer to in order to understand why his/her line of thinking isn't working.

Otherwise, a truly fantastic course. I 100% recommend it.

Getting to learn Teradata was a bonus. Great class.

That was a very useful and interesting class! Presenter did a great job, and her materials were very use helpful and relevant!

The most important and well designed Course I have ever done!

Great way to learn SQL querying and analysis strategies

This course really touched on all the most important aspects of learning how to use a SQL database while also providing many supporting materials for reference. I was very satisfied with the quality of the materials and teaching.

It was one of the most efficient courses I have ever taken. Thank you very much. I learnt a lot from all excercises.

Best course I've ever taken. Short but precise in the theory and lot's of practice on real data sets from real businesses.

If you work with data this is an excellent course, but even if you are not a frequent data user you can learn a lot from the logic it explains. I absolutely recommend it.

Amazing course and the quizzes are challenging. Learned a lot. Gives hands on experience on mysql and Teradata.

Great course great tools. Interesting and useful!

Challenging course with huge payoff in new skills gained!!!

Better than the one I took at uni! You really get to manipulate real biz data and learn from it!

Very useful:) Very good explained for the begginers:)

Best course to start learning SQL & Jupyter Notebook (Python). I have already tried to learn SQL from CodeAcademy, but this one is much more intuitive & detail-oriented. Lots of easy-to-follow examples, great instructor and quality of videos/lectures. I recommend it 100%.

Excellent exercises!

Awesome course, so clearly explained

Excellent MOOC. Ideal to get hands on experience with MySQL and Teradata working on real data bases. Great exercices and great professor. The last week is tough but rewar

I really learned a lot! But it's hard and requires huge amount of time to master.

Quite challenging, but a great course overall. The step-by-step exercises are great for learning the material in the sequential and organized way.

Great course until the end. The professor really understand the concept of teaching
