Reviews

I thought the course was informative and the tools to go over the material were very nice.

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

the course is good, covers many aspects, wish the lab is a little bit more in depth

This was a good program to get prepared for the solutions architect associate exam.

The training was good but needed the basic skills of maximo before getting deep in the configuration of it.
