The instructor should slow down when demonstrates the query and other calculations.

The course is great but I think that some conceps involving SQL are poorly explaned

Using BigQUery is tiresome. Many of the readings did a better job than the videos.

Advanced SQL concepts were just rushed and there were lots of bugs in this course.

The content could be more elaborate and more practice problems could be provided.

Instructor didnt do as good a job as previous instructors at explaining ideas.

there was some problem with the audio in several lectures in the course .

I found this course a little tedious... it felt like it dragged on a bit

Too many updates and changes not reflected in the videos and exercises.

some SQL stuff were really intimidating and hard to grasp at some point

Instructor goes too fast during examples without explaining the steps.

This course was a tough one, some of the topic were all that engaging.

Fast SQL teachings. Difficult to follow while typing the query myself

a lot of duplicate information wtih Process Data from Dirty to Clean

the sound quality was not good in this course in most of the videos.

not the best part actually really expected lot more in analyze phase

Too much google sheet usage, there is almost no tutorial about excel

regarding sql it was only samples not enough systematic sql learning

Not really well explained. Fortunately I had previous experience.

Some explain about SQL is a little ambiguity. But overall is good

Some of the materials of this course weren't working correctly.

it was more of the last course, not so much the analysis stage.

it was not to very hard to learn but there is some small small

many content semmed to be rushed or had misliding information

Lots of duplicate information in the videos and few exercises.
