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.

Another very interesting course, which helped me to understand some difficult new concepts. As usual the instructor presented the material really well, which made it easy to study for much longer than I planned to on each study session. Thanks!

Sally was very informative and enthusiastic, no one will ever question or think that they were watching the recorded videos. And even if the course itself is one way communication, yet it gives learners a great sense of classroom program.

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.

A​mazing 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.

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.
