I plan to get the RHCSA certificate as an individual.
Would highly appreciate any recommendation to free available resources for self-study. I can not afford to pay for training cources.
Thanks in advance
You should check objectives and focus on it as you prefer:
For example, you can take a very basic free course: https://www.redhat.com/en/services/training/rh024-red-hat-linux-technical-overview
You should be able to check the documentation for each objective: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/
