I loved the in depth knowledge of using especially SQL to clean data. I learned a lot. I didn't like or even study the week 5 content on resumes, it was abit off.

Explanation/examples of Nested Queries could have been made simpler and easier to understand. I had to go to youtube to get a clearer picture of how they worked.

Good foundation but I think if the course was broken down into smaller bits and had more practice items it would really allow the student a better grasp of SQL.

I like the course but it is really unorganized!

Loretta Your course is crazy I did 6 courses and only received credit for 3. your program really has no format.

The course is very practical and easy to understand although introductory. I have learnt a lot while learnimg and this has improved my attitude towards data

Huge learning curve for me as I went through all! Now I find the importance of keeping track of or documenting information as very valuable skill to have.

The process of cleaning the data was explained with good examples. However the SQL functions taught could be elaborated more with their alternate usage.

course is overall helpful, but i would like to suggest to put more effort into teach how to create database in SQl, import it and more on syntax of SQL.

I've gained many skills from this course including cleaning data like removing duplcates, correcting errors, removing extra spaces and many things.

It was another great learning process but technical learning like SQL can be more effectively entertained in simpler ways to gain deeper knowledge.

The practice parts for sql was limited with free trial of Sandbox.So I couldn't use some functions in query like UPDATE.The course was good though.

I really like this course learn and understood a lot of things .For SQL and Advance SQL I feel that should be taught more.

Enjoyed the rest course.

A LOT of information in this one, but feels great to put pieces together and start to feel like you are getting an overall understanding of things.

Good introduction to SQL and spreadsheet tools. Really good for initial exposure to content, but it is on the learner to practice what is learned.

If you are starting your career in Data Analytics then this course is for you and if you have experience in this field then don't do this course.

This course is excellent until module 4. Modules 5 and 6 seem out of place. Perhaps these should be combined into a single module about resumes.

This was a class that took us into a deeper dive of what the cleaning process is about and what to expect and plan for regarding data cleaning.

Useful information , simple explain & realty data cleaning Methods & tools , Really Thank You Both "Google & Coursera " for this opportunity .

I love sally she's different from other instructors she's actually enthusiastic and finally the course sets foot on something finally hands-on

I'd like to get some more practice using SQL queries and spreadsheets tools. Maybe you can offer optional resources to anyone that want it.

Great content! The instructor explains concepts really well and is very encouraging. I truly appreciate this course and the team behind it.

Just as awesome as the other courses I have completed, yet had some complexities happened as to activating the BigQuery paid trial version.

Very professional content, i enjoyed learning through it and understood a lot of new functions and techniques for data processing(Cleaning)

The third module is incredibly long to complete. It would be easier to "pace myself" if all modules were roughly equivalent in length.

A good course, that covers the important aspects of data cleaning. It is very informative and easily understandable, even to beginners
