RHCSA - how to get started

Hi,

I am a beginner and would like to become RHCSA certified. I would love to get some input on where I can get started? I checked out some of the official red hat training and it seems very expensive.

Does anyone have any recommendations for alternative training providers that might be more cost effective for someone like me how does not have a job as of yet, but wants to learn.

Also, is there a way to download RHEL 8 for free to try and learn for the exam?

Thank you.
