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.

Instructor is talent, but materials was NOT sufficient and took more time to search around. Course only focused on using one tool for SQL "Big Query" which half of functions could not be performed onto it due to free version available for education is only limited to "reviewing" functions NOT editing. I think we should have include other tools also as MySQL or PG. By the end of the course there was whole section about developing your resume which is way too early because they even mentioned "don't do this recommendations before to finish the course" then why the heck they show it in the middle of the course schedule? Also the course needed to include more practice on Github & Kaggle more than just reading links. Overall I did not relay on this course for cleaning data as much as outside sources. Please improve.
