Course - SQL Advanced level for Analysts

Gunnar adjusted the content for the second day based on our feedback from day one. He checked in with us to find out what we liked, disliked, found hard and how we wanted to approach day 2. I liked Gunnar's style of teaching: Lecture, share examples, allowed us time to practice and answer questions before moving to the next subject. It meant we could fully understand a topic before moving onto the next subject. This reduced overload of information and gave us a chance to spend more time on the topics we struggled with and less time on the stuff we found easy.
