A good course for learning and apply sql to conduct analysis on ab testing results. Would be better if the instructor could provide more info about how to design and apply AB Testing on the customers
The instructor is very smart and her syllabus is very easy to follow. The real life examples are great and helps put ideas in perspective! I would definitely recommend this course and already have!

The course is good. You will get to learn a lot from this course, as compared to previous Course(which is just the basic). The exercises are somewhat hard. Half of the time, it is due to ambiguity of the questions itself. You will feel frustrated on not knowing what to do. So, if this ambiguity is removed, the quality of the course can be improved. Further, the instructor should provide more videos/content on teaching SQL concepts which are neither taught in this course nor in the previous one but are used in the course.

The course was good and the curriculum was well constructed. My only issues are with the clarity of some of the questions, which I sometimes felt was lacking. A diagram showing the schema of the database used in the course would make things a lot clearer. Also, the peer-grading process is a bit of a mess. Instructions on how to make the final submissions accessible to peers should be made clear. I only got it right because it is a common question in the discussion forum.

I recommend the course in general. It has a combination of theoretical principles and hands on exercises in order to familiarize with the concepts behind the course.
On the other hand, I believe that instructions in order to perform and complete the exercises were not always clear which resulted in losing lots of time in order to try to decode what the actual expectations were.
But once again, a good course, giving insight in data wrangling and AB testing.

I had read comments about the instructors reviews that were distracting. But I actually liked a lot to see the construction of real queries in real team. However they were getting increaslingly complex and it was hard for me to keep up. You need a lot of practice on SQL before or during this course. Also, some of the instructions of the assignments were not clear at all. You can learn a lot with this course, but it will not be easy.

The practical aspect of this course is amazzzzzzing. I think the course is structured in a 'do-it-yourself' kind of style. The instructor does not spoon-feed, but as a student, you have to research the details of 80% of the material covered. It taught me how to understand data before working it, planning solutions before coding, thinking about what I am actually doing before doing it. The course is real.

The instructor was great, the course was amazing. It is a difficult course where you learn how to think about data and not just learn SQL syntax.
My only complaint is the lack of help in the discussion forum, the instructor does not seem to be active at all in answering quesions.

The course is very interesting and with a lot of examples and hands-on exercises. The lector is clear and makes very good presentations. However I found it difficult that the tasks and exercises are not very clear and definitions are sometimes vague.

Overall a really great course to get the analytical side of the brain going! Some of the weeks were a little too open-ended, though the activities were engaging and the solutions to the activities go above and beyond the basic solutions.

It was a great course. It was challenging but I learned a lot. I would recommend anyone who wants to learn advanced level SQL. But I would recommend the teacher to add some clearer explanations for the assignments.

The course was fine to refresh my SQL knowledge. The business cases are oriented on web analisis, which is new for me and I learned a lot of vocabulary and methos. Nothing super hard or challenging though.

In the peer-review part of the final project, the lack of answers and the lack of any updates to this issue from the staff knocked this course down from what could have been a very good course experience.
por Matthew P•
The course lectures and reading materials were excellent; some of the assignments were a bit unclear in terms of the directions. Overall I'd recommend the course.

The difference between the theoretical parts of the class and the exercises is insane!
But the things you learn are nice so worth it

the solution is not accurate enough with the real answer, it may cause some confusions

es un buen curso pero hubiera sido perfecto si estaría disponible en idioma español

The course was very informative and useful. I learned a lot taking it.

Was a tough one, but eventually made through after several attempts
the discussion board and peer review system seem unstable.

Interesting Course but a step below the previous one.

It was good experience working with SQL
