Reviews

Class was very informative, although one lab didnt but will try again later

ExitCertified provided great learning material and the instructor was great.

Easy to work with. Learning material pdfs were able to be printed out in color which was very nice to write on.

You get detailed labs to guide you through the technical material giving you a hands on method of learning otherwise difficult material.

Very good material, the instructor was clear explaining the topics, and the labs were easy to follow it.
