Probably one of the more technical courses of the program developing your technical skill set and actually preparing you to become a data analyst by introducing more hands-on Excel and SQL exercises.

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.

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.

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.

Every Sally's "Hi There!" possesses with a lot of motivational energy. I am falling in love with Data Processing, also her smile. For me who knew zero of SQL, She makes it easy to understand and wonderful as she claims.

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.

Excellent course materials.

However, in the end, it would be nice if there was a video showing the step-by-step cleaning of dirty data from beginning to end. I found other training videos that were very helpful.

Great and clear explanation, the instructor is the best so far. I have learnt a lot about using Excel and SQL to clean the dataset, but there should be more hands-on exercises instead of multiple choices questions.

The tutor is the best . Just one feedback ,the course could have gone little deep with the function and examples for practice . Also the Resume part could have been kept at the last after all the 8 modules.
