Very good and useful practice of SQL. The JOIN party is pretty hardcore so I definitely couldn't master it but got enough of an understanding where I could learn quickly with some on the job training.

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.

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.

This course is quite challenging especially when instructor too fast in SQL and skip the step. For beginner, I think its hard to follow but if they have determination to finish it, it will give them satisfactions.

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.

This was probably the most difficult part of this series certificate course. The content was great but the instructor and approach to describing the content itself was subpar compared to the predeceasing courses.

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

Creo que este curso es central en la certificación y el contenido no se explora en profundidad, además está desordenado, empezando con cálculos avanzados y hablando de cálculos más simples en el medio

I found a couple of questions on the weekly quiz were incorrectly graded.
Also, some of the examples used were not the best - i.e. the wedding gift registry - a real business example should be used.

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.
