While the class is excellent but there should be separated classes for Linux/Unix developers vs administrators. The class should also be 5 days instead of 4.

- attended our Linux Essentials class

4.94 out of 5

This was my first time taking a Certstaffix class. I found the pre-class registration good, notifications were good and timely. The class was started on time eachday except the first and that was not the instructors issue, it was the facility not opening timely. The instructor Alan Ricker is very knowledgeable, he has a good balance of humor and teaching skill to keep the subject interesting and fun.
