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.

some complex logic could have been more thoughtfully exposed

The course material was not upto my expectations. Thumb down

could have more example and workable work at hand assignment

BigQuery es un pesimo editor sql comparado con el TOAD

This is so hard especially in SQL, need more practice.

One of the harder part of the course very challenging

Errors with some sql codes, and instructor was fast

Explain more on writing query part. And logic.
