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.

The instructor in this course was great! This was the most enjoyable course in the program so far. Wanted to note: The Meer-Kitty PDFs in the coursse challenge are designed using a colour palette that isn't accessible. The colour combinations are painful and very difficult to read.

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.

This was by far the most practical hands-on course in the Google Data Analytics certification series. I thoroughly enjoyed the labs and gained much valuable skills in data cleaning. Looking forward to completing the remaining courses in the certification series.

Awesome course to keep learning about skills to clean your data and ensure integrity of your data to keep it reliable, this is not much like a theoretical course, but, indeed a hands on module, with lots of SQL functions as well as spreadsheets functions.

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.
