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

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.

Amazing course, the material covered is very useful, the instructor does a great job explaining the topics and keeping you interested and the questions test your actual knowledge rather than your memorization skills.
