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.

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.

I really like the course overall. The instructor is great. I love the videos and I think that they are some of the highest quality that I have ever seen on Coursera.

My criticism has to do with the quizzes. I honestly found the quizzes to be ridiculously nitpicky to the point of being almost funny. I'd watch around an hour of videos for a week, read everything, and then I'd have issues with certain mulitiple choice questions. Sometimes for the mutiple choice questions that require a single answer, I think at least two of the options are arguably acceptable, but only one is correct. It gets goofy when the questions overly emphasize definitions of non-technical terms which are stipulatively defined in the videos and then we get quizzed on extremely precise aspects of those definitions. In general, this makes the quizzes a lot harder than they need to be, but in a way that is artificial and doesn't really do anything to help us learn. You could learn this material, be able to do the SQL queries and data cleaning in spreadsheets easily, and then still have an issue with the quizzes. That ends up making a great course into a really frustrating experience.
