1. Instructor wasn't very helpful.

2. Some additional practice assignments would be nice.

This course dragged on and on. It was repetitive and some of the exercises had mistakes.

Until now I understand everything but in that course...no...sorry but that is my opinion

The course quiz had many wrong answers, and the instructor was not able to explain well

There were a number of times I stalled based on things that did not seem to work in BQ.

instructor voice is very low and some parts of this course is very hard to understand

generally good. some of the demostration are using spreatsheet and SQL are too fast.

I wish this course was taught by Sally. Her way explaining queries were much better.

Very rushed and all over the place. Not nearly enough practice to lots of new info.

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.

Please review my submission regarding content improvement for each sub-section.

too unnecessarily verbose. could benefit learning speed by being more succinct

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
