I really enjoyed this class and feel like it built on the material that I learned in the Intro class. Cecelia does a great job at providing examples for complicated queries that are easy to understand. I am looking forward to taking the Advanced class in August.

I was able to learn alot during the four weeks. The practice queries helped clarify what I had trouble with, and it all makes sense now. Can't wait to take the next class and apply the info learned in work.
