Very well organized and conceived. By following the course, I was able to learn and build on the concepts with minimal questions or frustration. It taught me what I was looking to learn, was well organized, and well-paced. I’m already applying what I learned at work.


The practical exercises were useful in offering ‘hands on’ experience. The interactive atmosphere and live examples used for illustration were refreshing.
