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!

Poorly designed course. Exercise are not good, instructions are unclear.
Wasted so much time to figure out what to do next, how to do it with unclear instructions.
Covered important concepts but couldn't practice them through

Not able to understand anything. Have to go through videos multiple times to understand what the lecturer is saying. No references, just talking and nothing else - worst course I have taken.

I am withdrawing from this course. The firs section was great with Sadie. The second, data wrangling, is very difficult to follow, feels very unorganized and without direction.

Very bad course. It's worst than the first one. The teacher intonation is not clear, just like she's humming by herself. The video they made sometimes are not updated

I don't think materials provided, especially for the installation of mode were correct.
I had to search how to use it on my own which took a long time.

bad teaching, you just see someone trying to improvise answers, its slow, some correct answers for test are in fact incorrect. Not recommended

Not very explanatory, it seems that is not taking into account the fact that most of the students are beginners.

Work on the assignments, define the question and more important point out exactly what's been asking for.

The course structure isn't well-planned. It is very confusing, messy and it didn't help me much

Poorly written and combined. Such a contrast with a first course in a specialisation.
