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.

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.

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.

I really had fun with this course. Very organic. I answered the questions with so much confidence I felt I was already a Data Analyst taking the course. Well done. I must say I haven't taken a course as thorough as this and at the same time simple.

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.

Really good in introducing more SQL commands, continuing from the previous course. Breaks down everything about cleaning data, especially appreciate the links to more information outside of the course that dives even deeper, if you want.

Fantastic course, had a good amount of activities in SQL and Spreadsheets.

Ms. Sally is the best instructor so far, she explained the concepts very well.

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.
