Good content overall. However it will be nice to have the glossary for each week not mixed up with those from previous as it makes it hard to navigate and know which new words need to be learnt

Sally's enthusiasm is infectious. But I'd expected more SQL hands-on lab using Qwiklabs. Where did it go as seen in previous courses?

A great opportunity to learn the basics of sql and spreadsheets. I think that the process of cleaning data is the most usefull part.

Decent overview of data cleaning in SQL and spreadsheet. Honestly, a bit lacking in actual skills application or skills training.

Excellent course, although I feel a little deeper explanation of SQL is needed for those that aren't very familiar with it.

A good course, however more SQL functions can be added which can be handy with informing of the nested statements in SQL.
