Must have

The Dojo courses are a great addition to AWS Certification. This one as well. That said, if you are only using this course for the real exam, it will be super challenging. In addition to these practice tests, there are several ReInvent videos, Twitch TV networking sessions, Cantrill, Stephane Maarek, and several YouTube videos which are a must. Dojo practice Tests are definitely one piece of the puzzle. Great Job on these Tests!
