Reviews

Instructor, Training material & span of the training is neatly planned.

The format of the class was concise. I learned new skills to use at my workplace.

It is very good and very simple instructions. almost to much hand holding.

The exit certified aws course provided a good introduction to the tools available on aws.

I think the platform is very good and look forward to taking my next course in early October.
