The content of the first two weeks were good and understandable, but for week 3 and 4 the teacher went too fast with SQL (I understand spreadsheets so probably if you are a beginner the functions she explained would be confusing as well...).

Did not feel like a beginner's class...

This part of the 8-course journey I'm going through is not bad, but it's the worst so far. This being said because of it's rushed rhythm. This was the only course that made me have to look for more information in another sites in order to fully understand what was being taught.

To be honest, the instructor was very bad. She was not explaining the SQL expressions, instead she was reading and speaking. Also many more was expected from Analysis phase of Data Analytics (Statistics rather than sorting and filtering)

Not happy with this part of course.

If you look at the forum, you can probably got a feeling of the course especially on the SQL material. The forum probably is biased as people tend not to post anything if they don't have a problem. Still I guess it's a valid peak to the sense of the course. Thank you.

This course is very heavy on external links for reading and learning. Some of the links go way beyond what was covered within the course. Tests are a step down from the ones in previous courses in the specialization. It feels like this course is not fully developed.

Example for subquery was so hard to follow, may be find a simplier case to explain what subquery is.

Do not use too many of the public data/spreadsheet, it is good to show how to upload but too many uploaded spreadsheet and use it for only 1 task doesn't make sense.

I feel like explanations in this course were a lot worse than in earlier courses. For example many explanations weren't visualized at screen. And Excel is a lot more popular than Google Sheets so it would be great to see how pivot tabels works in Excel too.

There were a lot of errors and I felt the instructor could have explained things better. Instead of writing instructions on how to type the sql queries, just screenshot the query and write instructions as to why we are using statements/clauses/functions.

In summary, this course lacks consistency in content delivery, fails to introduce new topics in the initial weeks, and poorly explains complex concepts like nested queries while overemphasizing simpler ones. I was too eager to finish this course ASAP.

This was my least favorite module. The instructor spoke too fast and went through examples too quickly. I had to rewatch and reread stuff over and over to get it. She also spoke too low it was hard to hear what she said most of the time.

Did not enjoy the tutorial guide on this one. A noticeable attitude shift from the bright and bubbly Sally before this course. This lecturer seems quite cold and a lot of the times rushes through the SQL/Spreadsheet tutorial prompts.

Terrible SQL course. Insanely frustrated with how they deliver the information, literally threw them at your face with minimum explanation on how the syntax work. Highly recommend other SQL because this course is a waste of money

SQL is something that they advertise everyone is using in the real world yet in reality the only people who use it are cubical workers in Napa Valley. Not going to use this tool for your line of work in almost anywhere you go.

Not enough practice with VLOOKUP and SUBQUERIES. Stuck on Subquery Lesson, example 1, step 15. I am copying the code exactly and not getting the intended results. Not sure how I can proceed or get help on this section.

The instructor is not well-versed in teaching. I was familiar with most concepts already and found minimum trouble in understanding the videos but for a person with little to no knowledge, it will be super difficult.

There were multiple times that the formulas given gave error messages, even when copy and pasted exactly. Frustrating because I couldn't finish the example/practice and didn't know what was wrong or how to fix it.

Some theory requires more practice and in some cases questions found in weekly challenge weren't related to "hands on" activities. I expected more guided practices and ask what was shown on videos or lectures.

La experiencia vs los otros cursos previos de Data Analytics es diferente, hay secciones muy sencillas y otras con mucha complejidad. Muy largo el módulo 4, sugiero separarlo en 2 o 3 módulos.

Terrible instructor. Concepts not well explained. Too dense. Instructor sucked at explaining things (and not because the content was difficult, but just because she sucks at explaining things)

Difficult to understand the instructor's methods of writing SQL queries. It was a hard time grasping the concepts. Her instructions felt to me as incomplete and difficult to understand.

It's not bad but telling people to review a video sometimes does not work , so can you please put the answer and reason. An if they're getting it wrong then maybe reference the video.

The course is all over the place, sometimes it becomes overly complicated and makes it harder to understand and sometimes it misses the necessary points which it shows on readings.

This is the most important course in the certificate, however it is not presented properly. In my opinion, this course needs to be up-to-date and prepared again from scratch.

The instructor went through the examples way too fast. For a beginner, I struggled to follow along, especially with this module being a little more challenging for me.

most of the codes don't work on bigquery, instructor reads the code with saying why we are using this and that, overall I didn't learn enough about sql in this course
