How to prepare for RHCSA for noob

Hey there everyone,

I'm someone who never touched linux and worked in customer support throughout my life, now with a few months there will be a new opportunity in my job where we could switch to a different team (non support role) but they need RHCSA holders.

I want to go for it but get overwhelmed looking at couses and confused by thousands of people teaching linux.

I understand pratice is needed but I need a good instructor who can teach me while I manage my night shift job.
