I wish there were alternative shown for people who use Excel.

It's an useful course for the basic concept of cleaning data

It should give us option to work on the sandbox version too

This is nice but more SQL example would be nice to have :)

The course challenged me at this point. Good one coursera

It provided great insight on how to clean data using SQL.

The Concat question in the final Quiz was very confusing.

I think it helful, but so many information not necessary

"It proved to be an engaging and enlightening journey."

Good course. The instructor was very good and technical

Good, but expected more of SQL and spreadsheet practice

Really helpful and easy to understand, great teacher !

Resume updating should probably be its own section

great it can be more vast but it's ok all the best.

Well structured but could be more pratical intensive

can include practise on sql,rather than in big query

Teach common functions in real life such sum,max,min

clear and concise lesson plans to help stay focused

Include more hands-on exersizes for using functions

Too many modules, same information being repeated

I did not get a good grip on SQL but it was good

I learned a lot not sure is it sufficient for it.

Excellent course but the content was repetitive.

Great. Most interesting chapter was the SQL one.

Guider needs to give more guidelines about SQL.
