The audio on the videos were extremely low on computers but other than that it was an excellent study the instructor did an amazing job.

Big jump in information. Agree with other commenters of the need for many more sql exercises. Otherwise this is just another article.

The teacher here is kinda, for lack of better word, artificial. The SQL side of thing is a bit convoluted and all over the place.

The SQL information and syntax is confusing and complicated. Additional practice or simplified material would be helpful.

Wonderful course! step by step instruction! It would be perfect if the instructor could explain further when writing SQL

There could have been more hands-on basic SQL queries to help lay the foundation before adding more advanced language.

Week 2 and 3 were very confusing and the difficulty and pace seemed way too different from the rest of the courses.

Course material is good but instructions are hard to follow, I have to re-watch and re-read a few times to get it.

Upon completing this stage of the course, I found it repetitive and not very innovative with the course content.

Sessions on SQL can be a little bit slow and detailed. She didn't explain certain parts of the query in detail.

In a lot of the sql lessons there is little time to keep up and work with the query along with the instructor.

I found the instructor a bit mubling, skipping steps in instructions and generally being difficult to follow.

the teacher is not so good at explaning also giving examples, her teaching method makes me a little confused.

one of the key database "citibike" is down, all cells return null, and some complex query are jumped to much

Voice of the instructor in modules 2, and 3 is inaudible. Else this course was the best decision in my life

There is repeated content, and the level sometimes increases too fast, while suddenly getting much simpler.

A bit disappointed. There's not much discussion about analyzing in general, only the tools used to analyze.

This instructor is not up to the standards of others. She has to revise the concept of DATA TRANSFORMATION.

In challenge section many questions contains many ambigous word that can lead to choose the wrong answer.

the trainer really ignore so many section and try to teach some section very quickly and unclear !!!

I found the jump from different levels in SQL knowledge in this particular course to be difficult.

There are several mistakes in this course and the instructions are not as clear as other courses.

Instructor instructions sometimes needs more explanation in comparison with previous instructors.

I wish there were more complex SQL and Spreadsheet examples. But overall it was a good course.

Some of the data is not indexing, it's hard to search

And some of the learning is inconsistent
