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.

Google makes great professional certifications. All the classes so far have been fantastic but getting our hands dirty with the data was fun and challenging. Look forward to completing this series.

A great course on data integrity along with the applications of SQL and spreadsheets. Have learnt about SQL in college, but this course has really taught how it could be applied in huge datasets in Google's BigQuery as well as the different methods to clean data using SQL.

This was a great course on the whole. It still suffered from some of the same issues that this whole certificate program has had, such as vague multiple-choice/multiple-answer questions, but the presenter was very informative and I learned a lot about SQL in particular.

This course has been very helpful as it builds the basics of data cleansing, its objectives, and how to execute it effectively. It not only teaches the technical skills needed, but the soft skills as well to communicate and coordinate data cleansing with others.

The best part about this course was the resume help! I wish every school program would incorporate a section like that into their programs. It's so helpful to know how the skills you learn in the course can be applied to resume building and job searches.

I will be honest and say that Week 3 of this course made me question if I was ready for data analytics! Lots of information, but I made it through it. I really liked Sally as an instructor! I hope that she is teaching another course in this program.

I just loved this course, to see sql on the Big Data section on google dashboard and practicing my query skills on sql was really satisfying, This journey in the way to become a Google data analyst certificated is being more amazing than I thought.

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.

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.

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.

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.
