Every concept they explained crystal clearly and thoroughly. I am so happy that I am learning all these courses at free of cost. As soon as I get data analytics job, I will pay the fees without fail.

Good overall. I'd like a deeper or more technical view of the statistical concepts for data testing, or maybe some more practical hands-on problems in which you are required to calculate those to provide the correct answer.

Overall I loved how enthusiastic the instructor was and her humor as well. There were a few sections I did not quite understand and had to do some outside research for but overall it was easy to follow and understand.

I found the instructor personable, enthusiastic, and a clear communicator. Topics were presented in a logical manner, and at a great pace. I wish there was more SQL instruction, but I'm grateful for the career advice.

Some content can be explained in a bit more detail. For example, there's an explanation that SQL can track changes, but how?? Also, it would be best if some of the multiple questions can be checked again for accuracy.

Le contenu concernant le language SQL est intéressant, mais les partie telle que les CV et le recrutement sont de trop. C'est très long pour des notions qui pourraient être condensées avec du contenu plus court.

There were few spreadsheets' tools definition with no explanation of How does this formulas or functions work in order to perform a task or activity, would help a lot same for SQL, how does these software works?

A hands-on approach with various technical features, mainly regarding spreadsheets and sql. Interesting exercises with guides, its just unfortunate that mentors seldom answer questions effectively in the forum.

I learned a lot, but I think it would be better if you made the quizzes/ course challenges more practical. Instead of asking what the learner should do in a particular scenario, make the learner actually do it.

It was a fundamental and intense course, but the only disadvantage is an endless try to login into Google Cloud Platform for the sake of using SQL, which usually kicks you out due to some limitations, etc.

I learned about the importance of cleaning the data in order to carry out proper analysis and conclusions. Also about the importance of preparing my resume and clearly expressing my skills and knowledge.

Very informative and practical. It's a bit harder than the previous, but with the bite-size approach, it is less intimidating. The teaching method by Googlers is less dry than most academics at Coursera.

Awesome couse, explanations were very clear and concise and all the readings weren't loaded with unnecessary information. To make this a 5 star course I would add more SQL excercises for cleaning data.

Sally is the best instructor in this course so far. The content itself started of great but I feel it didn't cover enough data cleaning techniques in the second half of the course. Still recommend!

It is better to use more hands-on exercises. Some of the obvious topics repeat itself several times such as removing the duplicates. Some of the multiple choice questions have vague answers.

The SQL and data cleaning exercises were fun, but I think the resume building was brought in prematurely. Those topics would be more informative and relevant nearer to the end of the course.

Explications are clear but i think there is a lake of practice about cleaning a dataset. It would be better for learner like use to have more of this kind of complete exercices to complete.

This course was ok but 2 of the last weeks were job interviews and writing resumes. Which don’t belong here. It should have been an optional mini course if you complete the certification.

Some times very repetitive , and some examples are not so clear , it would be better to have just one big example , so as we progress we start to understand the full picture of the data.

4 stars because there are consistently errors in the weekly challenges and quizzes that make the learning process frustrating, and I lose a bit of confidence in the course as a whole.

Does not go deep. The main takeaway should be that they're showing you the tools you need to start your DA/DS/DE journey, but you need a lot more practice to master each tool.

This was probably one of the more difficult sessions. You really must pay attention to every detail and really go over the exercises to make sure you understand the material.

Some of the module videos need to be updated. A few links could not be accessed, there were a few pop up windows correcting updated information that did not match my screen.

Could use a little more practice on the Spreadsheet and a little more explnation on the SQL functions. But apart from that it was good, much better than the previous course
