An excellent course for learning analysis techniques using Spreadsheets and SQL. Recommended for all engineering and data science students as well as for those managing businesses and human resource.

subquery examples were unnecessarily complex. ultimate course design and deliverables were up to the mark no doubt. more detail and easy to understand technical examples would be much appreciated.

The topics are great, but the instructor went super quick and also in some parts was just silence, and she just put the query without a proper explanation. Love the instructor of course 4 in this one too! She was so nice and easy to follow.

This course suffered from many more editing errors and weird sound than the others. I also felt like the way it taught SQL was really surface level. Lots of copy-pasting and less problem solving. The links to extra practice were essential.

Had some technical issues with the videos. It kept bouncing back to the start of the video. I faced difficulties to follow the syntax as the instructors did not explain it clearly and moved to next steps too quickly.

Some errors were found in the course. I suggest breaking sections into another week to digest large/hard information in week 4. Also, some content needs further elaboration such as the use of subquery, Temp table.

while i learned a lot, it was struggle to keep up with the instructor. A lot of videos were info dump and i had to do a lot of side reserach to understand what the function is. She was also quite fast

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...

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

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.

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.

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.

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.

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

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

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

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.
