The instructor was very knowledgable and friendly and the hands-on labs are a very good way to learn.

The structure of the materials and labs is very condusive to learning. I appreciate that the material doesn't feel like it is desined to trick me. It does a good job of preparing me to take the test at the end.

The training (materials included) are very useful for real life. The materials will be helpful in the future too.

I liked class participation the most. Observing other people actively learning also encourages me to think critically and learn also.

This is the second time the Phil has been the instructor for me, he was my instructor for my RHCSA. I would gladly have him be the instructor on any future RedHat courses.
