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 m贸dulo 4, sugiero separarlo en 2 o 3 m贸dulos.

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

the material needs revising. The instructor skips many key steps in the vedios leaves the student in doubts

. Could have been introduced in much better ways

This course really needs improvement. It's a shame that one of the most important courses of this program is at this mediocre level.

Lack of data context and too fast pacing.

Not at the same level of the other 4 courses i took so far in this specialization.

I dont think it was well planned and it went too fast for my taste. I had to learn SQL first on data-camp to make it easier

SQL part was a lil bit too fast, the instructor didn't go through in details. And using BigQuery is a little bit dauting

I didn't feel like I learned how to analyze my data. Was mostly repeat information from other sections of the course.

This was difficult.. I cant really use Query anymore because they want to chage me to add space to my free account.

The instructor was very monotonous. It was very hard to pay attention as the delivery was very robotic like.

SOME OF THE SQL PARTS NEEDS TO EXPLAIN BETTER THAT I FEEL. PLEASE DONT USE BIGQUERY. IT IS A COMPLEX 1

it mess information about the analysis it self and just teach you how to use tool in very basic way

Out-of-date instructions and an unexpected requirement to buy BigQuery and other programs.

Some of the explanations for the BigQuery SQL exercises are not clear and very incomplete.

There is no longer any explanation of SQL in module 3. Believe me it is an awful section.

it could be easily merged with the previous course. Not much-added information here.

Nobody uses the console Sandbox. Please update the course to sql Microsoft server
