This course is way too outdated. I did learn a lot at once, but all of the examples need updated and there needs to be more theory on the "Why". Too often I felt like I was just copying the instructor because they were not explaining anything while entering queries.

Overall, a good course, but in some VERY IMPORTANT parts, the instructor was very quick to explain and skip steps ASSUME that we already have this knowledge. I also ask you to update topics, since for example VLOOKUP is now easier and fewer errors when using XLOOKUP

I didn't realize which one part was about analyzing data. It actually was the same information from previous lectures a little bit extended. It confuses, perplexes and tangles when you are receiving repeating SQL clauses named as an analyzing content.

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.

Sometimes felt like I was learning SQL backwards from how I should have been. Learning operators and basic math functions practically at the end of the course felt wrong and not helpful. This wasn't as well structured as the other courses.

There is too much packed in one course as a result there is no justice done to any topic. May break this course into at least 2 parts.

Plus the topic of data validation is covered again which should have been covered in the earlier courses.

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.

Could have been better if few topics were not forcefully stretched and make it boring or irritating sometimes. Few things were repeated unnecessarily. Would have been happy if things were made a little interesting. Rest overall was good.

The instructor was skipping functions and was too fast with the lectures making it hard to keep up with. The course opened up with many useful contents to get familiar with SQL and Spreadsheet, but the instructor made it hard to follow.

Compared to the other courses of the specialization so far this was a bit confusing as it suddenly introduces SQL queries or formulas that were never mentioned before. In any case, it still helps you learn a lot of new stuff.

The audio during this course was not as great as the previous courses. There were also many errors throughout the course and also many errors during the final course challenge. It makes learning as a beginner very difficult.

I felt that this was the weakest course in this certificate program so far. A lot of the example code had syntax errors (lack of proofreading perhaps), and some of the code didn't seem to run properly in BigQuery Sandbox.

Easily the most difficult so far. However, this is mostly due to the clarity of the content presented and the order it is presented -not the concepts discussed. Use the included resources and forums to avoid frustration.

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.
