This was a very fun course! I really enjoyed the style and pace of the information given. A lot of technical information was given while the course made it easy to take in and comprehend the material!

I loved this course. When I had issues support was awesome sauce. I really enjoyed the puns this instructor used to keep you from going off in a daze. I really wish I would have found Coursera sooner.
