I love Sally, I can tell she is passionate about what she is teaching. I really hope I will take more class with her. And I like this course as it talks a lot of knowledge about data analysis.

Would be helpful in the examples to have a split screen showing what the SQL queries are referring to, saving the mental note every time an explanation is happening

I had a good experience with the course and liked the hands-on activities and tutorials, the only problem I faced was using BigQuery because I did not have a card.

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.

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.

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

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.

Sally's enthusiasm is infectious. But I'd expected more SQL hands-on lab using Qwiklabs. Where did it go as seen in previous courses?
