Very difficult to follow

change the instructor.

Need better trainer

too little of sql

By far the les

Nice!

This is genuinely the most confusing lesson I could imagine with almost no explanation from the course instructor. I am specifically referring to the sections on aggregate functions and subqueries (week 3), though this entire sections has been rough and confusing.

This is very complicated coding for a beginner (this course's target demographic) and it is breezed by with nowhere near enough explanation as to what these queries accomplish, how and when to use them, and how to format these queries. I took a different SQL coding course before this course and this lesson has confused queries and concepts that I had decent comprehension of before taking this lesson.

On top of all of that, BigQuery uses different dialect and formatting than any of the other SQL programs and servers that I have used. It also is very buggy and doesn't operate as indicated by the weekly lessons. Oftentimes the weekly assignments' instructions are outdated and need addendums to each step of the instructions, further confusing the concepts.

The instructor seems to be out of pace, especially at week 4.

Especially when it comes to SQL, at the earlier weeks, she adds too many things that weren't mensioned before which caused me confusion and lead me to look up every previous material in the course which resulted in me wasting my time.

It was good for me, cause i looked everything up on my own. But it wasn't good for the course experience i.e having to put into account that the instructor might introduce things unexplained and are also complex.

I might sound like being irrational and over inflating things but compared to the "prepare" and "process" courses in this series, this one is a big leap backwards when it comes to the instructor and the way things ,that are to be given to the student, are ordered.

The lecturer was quick, not thorough with her explanations, and generally, felt like she just wanted to rush through the topic. The examples she used in her explanations a majority of the time did not work, which I then had to look at the discussion forum to find solutions for. Overall, I found the other courses to be done quiet well, It was concise, explanations were thorough and the examples were spot on, however, with this course, I was very disappointed. I had to do most of my own research for the topics so I could learn on my own. The lecturer did not help.

Instructor very fast and she doesn't give detailed explanations to what she is solving which really demotivate me and when I checked many also say same thing on our discussion area and there is no actual responses from your side all they say (thank you for your feedback) is that all so actually we didn't feel any steps taken maybe your company actually is taking steps in this regards but we will never know if nobody tell us which in return actually give us not good image of coursera

did not care for the instructor at all. most of it was probably tied to the fact that several times incorrect codes were given and it would take multiple hours to figure out what actually needed to be put down. Made several complaints about this in reports and never heard back. Even found a group of people who were searching out the answers in stackoverflow and found some. there were entire missing lines in the SQL code. please review your Bigquery codes for this unit.

Terrible. The instructor does this way too fast and provides the most excruciatingly confusing examples. I tried accessing public datasets from bigquery and it kept saying "url not found". So i tried contacting Google Cloud support, which was literally impossible. I actually think I would have somehow learned more if I had not taken this course at all. This made me want to completely stop trying with the professional certificate and now I honestly want a refund.

No STAR at all.

Coursera.org and Google are great, but this course seriously needed to be revisited and all the videos and content to be reviewed and synchronized.

the teacher is very professional and knows her subject BUT she is not a teacher by all means.

please replace the teacher and revise the course with the latest CLAUSE please.

I am grateful to GOOGLE and COURSERA.ORG for providing me with great professional skills.

I'm only rating this way because I can't rate the entire Google Data Analytics Professional Certificate. I just wasted 6 months on this course with the promise I could get a job in data analysis. Well, I can crush data analysis! But my lack of background in math is proving to make me unhirable. I wish I'd known this before wasting time and money on this program. Now I'm 6 months behind training for another career.

By a longshot, this course has been the most poorly executed in the Data Analytics curriculum. The teaching versus the exercises were nonsensical. For anyone new to data analytics, SQL or spreadsheets, prepare to be amazingly confused. The sheer number of corrections in each video should have given the QA team for this video, pause. This section needs a complete overhaul.

The content of this course was neither explained very thoroughly nor presented in a way that was easy to understand. I found myself looking for a lot of other resources to learn some of the topics, especially SQL subqueries. Upon requesting for assistance through discussion forums, I discovered that many of my peers also taking the course were equally frustrated.

I learned a lot from this course but it was a nightmare. The instructor moved extremely fast through the important parts of the code writing and examples. I had to pause each video countless times and rewind just so I could figure out what she was doing. Also, not enough explanation of what she was doing in each step. All the other courses were at a great pace.

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.
