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.

The instructor in this course was great! This was the most enjoyable course in the program so far. Wanted to note: The Meer-Kitty PDFs in the coursse challenge are designed using a colour palette that isn't accessible. The colour combinations are painful and very difficult to read.

A great course on data integrity along with the applications of SQL and spreadsheets. Have learnt about SQL in college, but this course has really taught how it could be applied in huge datasets in Google's BigQuery as well as the different methods to clean data using SQL.

This was a great course on the whole. It still suffered from some of the same issues that this whole certificate program has had, such as vague multiple-choice/multiple-answer questions, but the presenter was very informative and I learned a lot about SQL in particular.
