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.

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?!

The instructor is good but there is a drop-sync with the exam. We are taught to use UPDATE to add customer information; that is marked as wrong on the exam. The substring link to refresher does not contain substring directions. Please review.

I needed more time to complete the course than was allowed on the big quesry free trial. there should be a longer subscription that comes included with this course. I also dont need resume help so it would be nice if that section was optional

I felt that the course was not designed well for the sandbox, very often while following along I got errors like

DML queries are not allowed in the free tier. Set up a billing account to remove this restriction.

This was frustrataing.

Barley any material to work through. If I was completely new I'd barley learn a thing. The instructor is great but should provide more training excercises. ex Codecademy's coureses are so far VERY much superiour in their teachings.

I think the content is good but the flow of the course got scrambled. not sure how but. it seems the one is finished and the next is only partial but it seems the system does not want to move off this one.

Wasn't iterative. I don't know if it was the course instructor or what. I'll just have to supplement my learning with other resources.

Final test was unclear and half of the course is about finding a job in data analysis not about process data or anything related.

The speaker of this course needs to explain what and why typing whatever is typing there. It is very confusing.
