Build a service offering AA solutions to customers

I’m completely new to Automation anywhere, but have some high level familiarity with RPA. Unfort i lost my job and looking to reskill. 

I was interested in learning this application and potentially add this to my IT services by helping customers implement this. I also plan to build bots for usecases.

What is the best ways to get started?

I can start taking the training programs. Is the exam free?

Any feedback else on this path would be helpful. Thanks.
