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.

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.
