I thought it was very redundant and didn't really teach new concepts too clearly. It went over the same information multiple times which made it seem as though I wasn't actually learning new skills.

Compared to the other parts of this course this was the least preffered part as it was a bit too quick for a biginner and was not detailed. i took longer to understand what the lecturer was saying.

Some mistakes from the instructor that had to be fixed in prompt.

Some sql clause examples were confusing and were only explained in the later section of the course.

The TV was not even straight...

Instructor spoke too fast, lots of errors, codes were not explained properly. felt like everything was rushed through.

Ask, Prepare, Process modules were explained well. Disappointed with Analyze.

It was way to fast an explanation. Instructor should have gone slow while explaining difficult queries. This was by far the most difficult course purely because of the way instructor taught.

The instructor just wants to rush the course to finish. I do agree she has a sound knowledge of SQL but she was coasting through the course. Wish Sally was the instructor for this module.

I found it a little lacking in technical tools for this matter and much like past courses. I think this is the first course that needs improvement. Make it a bit harder but more useful.

The Videos regading sub queries broke the established speed at which all the courses have been going, was better towards the end of the course, but that section was difficult to follow

Significant amount of material is incorrect, which will waste your time attmpeting to troubleshoot why your code isn't working. Also, there is alot of repetitice spreadsheet content.

Quizzes seem to be not quite closely related to the course materials. A bit confusing and the structure is not rather clear comparing with other courses in the specialisation.

Big query works differently from what the instructor is trying to do. Instructor is going way too fast and frankly looks a little intimidating comparing to the previous ones.

a lot of exercices I could do due to limit permissions. Hands-on was not really hands on - I suggest to refresh and improve the content if this course has to be still good.

This course was very repetitive initially, teaching us the same things that we had learnt in data cleaning lessons. Then suddenly there was a whole of information dumping.

I felt the SQL lessons of this program is quite fast and it was hard to catch up with the pace. Perhaps, if the lessons were better explanatory it would have been better.

My experience of Analyze Data course mixed-up. There are was some weeks that didn't get you a new information and only repeat old knowledge from previous courses.

the course was good. full of things that were new to me. however it was going way to fast at some parts. especially the SQL parts. but manageable. 3star is good.

Dense course on short bursts of information.

Technical problems with the BIG Query. If you don't have time to search for the answer, probably you won't get it.

Week 3 was loaded with insufficient explanations, and I've also noted that the guidelines on SQL syntex introduced in Course 4 was not followed in this course.

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.
