I'm glad I took this course. The instructor is warm, upbeat and very clear. The materials are very informative and helpful. I gained more understanding of cleaning data as well as built my SQL skills.

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.

Some hands-on exercises are inaccessible to the user. Had to write to google labs for every assignment dataset, which they sent me to my email.

Too much information crammed into few modules. The course would be better broken down further to one or two additional modules.
