Reviews

Great class I learned a great deal from the material. There would seem to a large amount that I need to learn about.

Topics, material and specially instructor (Graham Godfrey) was beyond my expectations.

it was good and very informative. Instructure covered everything in detail.

ExitCertified gave me some good trainings and I got to learn through doing labs.

Class was easy to sign up for and ExitCertified provided very good communication
