I was a very interesting course. Definitely going to check out other classes they provide. Great place to help prepare for certifications that i plan on taking within the next coming months.

excellent instructor very good experience valuable for my next project
By Robert S.
Perfect pace for the team. Covered all of the necessary materials. Instructor was able to capably handle student problems in lab. I had no problems, but I am a very experienced Linux admin. I advise everyone to carefully review the prerequisites, because they are essential for completing this class. It would be nice if there was someway for students to capture the Skylab/VMWare setup. I'm sure that I am not alone in wanting to be able to setup my own lab.

Pace seemed a little slow, but that's probably due to the wide range of student exposure to DOORS.
By Tony V.
Great course content and delivery. Sets up a good foundation for using DOORS as an end user.
