I'm enjoying this art of the course but it does seem to suddenly leap into more complicated SQL quite quickly, a few more basic queries would be good first.

some videos are of poor quality and the lecturer skipped explanations for some complicated syntaxes and queries but waste a lot of time on simple functions!

The weekly challenge 4 is too hard and I already did the weelky course challnge please tell me how to finish this course withou hvaing to do this again.

This course mas a Little difficult to follow..some thing not well explanined ( over all SQL) ..and looks like the teacher was Rushing in some parts !

There are mismatches between the data displayed in the videos and the data in the supplied sources. This makes the topic of SQL harder to comprehend.

This course was below par as per the standards of previous courses in this track. Some of the questions in quizzes were very difficult to comprehend.

Perhaps this topic/part should be more than 4 weeks and more detailed or more projects and assignments. Felt like its started and ended immediately.

actually i think the content of this course it's kindof repetitive, we have already seen some the majority of it's content in the previous courses

Subqueries in week 3 a beast and were not adequetly explained. It didn't help that BigQuery had instances when it gave out ridiculous errors.

the pacing of the course is quite fast, i am too much overwhelmed by the examples particulalry in sql. Please make it slowly and in details.

She is a good instructor, but I wasn't able to understand the JOIN in SQL from her, so I took another source to understand it

Thnaks anyway

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
