The worst course I've ever done in Coursera. Videos and exercises felt very low quality and put together in a rush. Half the course is trivial and brings nothing new. The other half introduces new concepts without any context and makes it very easy to get lost.

I am also unhappy with how little attention the discussion forums receive, so good luck if you need one of the organizers to solve an issue with the assignment.

Course was ok overall. I learned the basics and the SQL was good. I learned a lot about the basics of SQL through the course. However, the video could have been better edited and the prompts/questions (especially in the final project) were difficult to understand.

I'll give it a 5 mostly because this is one of the few in-depth SQL courses on the site, plus it actually goes beyond Joins and all that other pre-advanced stuff. I actually learnt new methods such as using windowing functions and using AB Testing. It could be better yes but we need more practical courses like this one.

Great course!! I have learned a lot about how to evaluate the quality of the data received, how to problem solve with SQL when asked ambiguous business requirements, tips to do multiple selection editing in text editor (that was a great discovery!), metrics and AB testing. Highly recommended!

The assignments are pretty difficult, and I think this course suits those who have advanced SQL skills and wanna use SQL to solve higher level problems. The lecturer are pretty interesting, and I enjoy that.

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

It is pretty useful course to understand how to prepare data for AB Testing in real database environment. you should know SQL intermediate leve before starting this course.

A very thorough overview of SQL and how to best structure data tables and metrics for AB testing. I appreciate the high quality content of the UC Davis courses!

Gracias por impartir conocimientos online y darnos la posibilidad, a quienes trabajamos seguir perfeccionándonos, organizando los tiempos personles

Good course but a little more challenging for me as a beginner and new to SQL. Overall Good

Amazing work guys! I enjoyed the coding part a lot. Thank you!

SQL, Data Wrangling. Challenging and fun course.

Well executed and scripted for learning

Challenging, but I learned quite a lot.

Very complete course! Thank you!

Really professional!!

Interesting Course

useful course

Excellent!

excellent

fantastic

perfect

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.

La profesora es agradable. Las primeros módulos son la continuación del anterior curso, se aprenden algunos comandos más. Algunos ejercicios requieren comandos que no se han visto pero en los videos de solución los muestran. Recomiendo leer bien la página de ABBA (ellos te dan el link) para entender mejor en qué consiste el AB testing. Me gustó la plataforma de Mode Analytics.
