this part was the most important one ,i think it is the difference between the theoretical and the practical, between what you arrange in secret and what will appear in public. I think it did not receive enough explanation and practical examples. I think it would have been better to divide it into 3 parts between different lecturers.

Its the least useable course so far. It has lots of repeated contents which have alreay disscussed in the privious courses. And the analysis techniques covered are short and weak. I can't beleive those are the only analysis techniques that are worth to discuss for a junior DA.

most of the tutorials are outdated or in correct and then they have added pitstops where after some time they tell its wrong do it this way to get the result ! took most of my time and also confused me ! just paid for it so just hanging on never making this mistake again .

This instructor is way too fast, skips steps and does not answer any of the questions I am left with. I thought the JOIN section was attrocious.

Also, one of the datasets on citibikes just returned a full set of null values, I could not do anything with the dataset myself.

I am not impressed with volume and the interface, I am work on bigquery, my interface is different from that of the instructor the features such how to query setting is not showing on my interface ..

on how to save and create new table and it has taken a lot of my time.

so many mistakes in the lecture, and the instructor is really not organized...Please don't write scripts that don't explain the key knowledge points. I had basically learn everything from W3School instead, what's the point then?

When I the course provided me the syntax that it wanted me to you use on Bigquery, results would come back denied. It was just too many to go though cases like that and it was hard for me to keep up with the course.

Compared all the course, this specifically felt tough. I have prior knowledge of SQL, but still felt it was difficult to follow along. Easier examples could have been used. First poor review from the entire course.

The way of explaining was brief to me about the difficult things in a lesson Subauerv

In practical tests, the examples were much more difficult, than the video explanation, supposed to be consistent

It's very difficult to follow the explanations, so far the worst part of the course. The teacher speaks very quickly during applications in spreadsheets and SQL - Some functions don't work

The instructor in this course is needlessly confusing, and assumes you know functions you have never seen, which then makes it really hard follow along on some of the activities.

i give 0 stars to this course because the instructer covers lot of topics without brief explanation. few concepts i couldnt able to understand, it went above my head

These courses have only gotten worse as they've progressed. Unfortunately I already gave 1 start for the previous modules so there's no lower score I can give.

The instructor for this course doesn't explain all the steps thoroughly and leave the audience blank, please use the videos for this course.

the instructor doesn't explain very good, and she is fast. Needed to rewatch all videos and that took me time. " point of view" no offence.

This is by far the worst of the series. no shade to the woman but I was so disappointed that I almost stopped watching it

I find this module monotonous because there were just a few hands-on activities compared to the previous modules.

the worst instructor so far in this specialization. i hope she wont be teaching any of the next 3 courses left

As someone working with SQl on daily basis the way the queries were explained on week 3 were too overwhelming

I would have appreciated a more thorough and detailed explanation of the complex queries from this course.

needs to be divided into 2 courses one of them SQL and to illustrate slowly with more examples.

This section needs to be updated. Almost every hands-on challenge has at least one issue.

The lady is so clearly not a good teacher and not much interested in what she teaches.

The course has a mistake in one of the challenges. So, 1 star will be enough

Reviewer spoke too fast and didn't explain their work as in depth.
