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.

All the previous courses were good but this one with Sally was really interesting to keep going forward more often. QwikLabs are great. Need more QwikLabs for extra practices.
