Reviews

Very good couse and again we would like to see more videos on removing FRUs

Good training material and good instruction. More time needs to be provided for the lab work.

The class covered the concepts needed for the AWS Cloud Practitioner Certification.

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

Course was great and informative. The instructor had a good flow and was very personable.
