Really good in introducing more SQL commands, continuing from the previous course. Breaks down everything about cleaning data, especially appreciate the links to more information outside of the course that dives even deeper, if you want.

The instructor was very positive and thorough. It was encouraging to always see a smile on her face! She was very effective in her teaching. Her rate of speech was perfect for getting the points across. I hope she teaches other courses!

I really enjoyed this course. I was exposed to many new functions I was not aware of in both SQL and in spreadsheets that are used to clean dirty data. And not to forget, Sally is an amazing teacher! Loved her positive energy and jokes.

A very good course on how to clean the dirty data, with the help of tools like spreadsheets and SQL. Cleansing the data is very important for the accurate analysis. Dirty data can lead to the catastrophe of the planned business result.

I loved the instructor great personality. I wish that the hands on activities worked for me but they kept pulling syntax errors even when using the copy paste feature. Please fix so that new analysts can learn effectively. THANK YOU!

Fantastic course, had a good amount of activities in SQL and Spreadsheets.

Ms. Sally is the best instructor so far, she explained the concepts very well.

Room for improvement: Less Multiple choice questions, more Hands-on Activities

Compared to the previous courses, this one was a little bit more challenging, but I think that's more to do with elements I wasn't too familiar with before starting. The instructors, however, made the learning process so much easier.

Thorough and comprehensive building blocks. Makes it easier to learn on your own once you have a clear idea about the key aspects to focus on. You can build a framework and follow best practices to work faster and more efficiently.

This was my 4th course and the instructor explains things really well. The things discussed in this course form a key aspect of how to make the data ready and clean before starting analyzing, which people may not pay much heed to.

This course went very in-depth into SQL and BigQuery. They presented SQL in a way that was not too intimidating for a beginner. This course had less discussion prompts and more in-depth videos which I thought were more helpful.

I liked this course very much. It didn't go too deep or get too confusing. IT had just the right amount of basic instruction and plenty of easy to use links to keep in my library for reference when I get into the real world.

I liked that the course gave us some of the concepts that are not found on the internet regarding SQL and highly recommended to see it more than once to get a proper understanding on each function to understand when to use it

Its an extraordinary course but it's been presented in very easy way that even a person like me who don't have any background in computer science have understood the tools and functions easily. Thank you google team.

Fantastic course but somewhat too basic for a person who had any experience working with data. But I understand that this is the whole point, getting people stated in the field of data analytics requires diligent guidance.
