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

The corse had great information but was the least helpful in explaining how to preform tasks.

No need to teach excel from scratch again. It was already taught from the pervious lessons

I felt the course are getting harder and harder to follow up, especially with SQL queries.

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
