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.

Unfortunately, I have to say that this has been the worst course on Coursera I have taken so far. First of all, you are often confused and lost during the lessons (because the step-by-step are not well explained when tackling new functions/tools). Second, it took more than a week for someone from staff come and answer one of my comments on the forum (and in the meanwhile some other student wrote that they were facing the same issues and no one would answer them)! Finally, during the videos it keeps poping-up messages about what the person in the video forgot to say, or that there was a mistake in the code line they wrote in the video, or that a peace of information was missing (it's really low level). I mean, this is one of the most famous courses on Data Analysis and it should be much better. I give two stars: one for the person instructing (because she is funny), and another for the tasks that help understanding the content.

Like all other courses in this certificate so far (this is the 4th, I'm super disappointed that the course material is still focusing on common sense/common knowledge instead of actual practical skills in data analytics. Direct teaching statement from the course "If you need the data for female voters and received the data for male voters, restate your needs" -- seriously? Students don't need a word by word approach to how to generally function in a work setting. The content of the course is wasting time that students could be using on actually learning data analytics skills, from other providers.

I loved the SQL part however, About Big Query watch out guys I had an issue with my billing and honestlly I think that considering we are here learining making you add a credit card to write data into google big querry is a shame, they should let us know that the tool only allows read and not write therefore not all excercises are available for students.

complex example used made it more difficult plus the method showned in big querry were not curent so could not follow and understand when i was using big querry . OUT OF ALL THE COURSE FINSED 6 IN PROFFESTIONAL COURSE THIS COURSE NEEDS SOME SEROIUS EDITING . FOR FIST TIME LEARNER THIS COURSE IS NOT AT ALL EASY

RESUME PART AND 4 AND 5 WEEK ARE GOOD.

SQL queries sometimes work, sometimes don't, which drives you crazy because you don't know if you are doing something wrong when you copy and paste and it still will not work, many hours of time lost figuring out what might be the problem, and the problem is the course. I guess the course is not updated.

This course was 90% tedious videos and readings. The lack of hands-on practice to solidify the skills covered was frustrating. For instance, 3+ videos on "why changelogs are important", followed by a brief reading on IMPORTRANGE, QUERY, and FILTER functions with zero application?!
