Coming in from another field
You do not need a security job to start. Begin with the exam's published outline. Then work the hands-on missions in the order your own record points to, starting where you have shown the least. You finish with a record you can walk into an interview and talk through.
Already working in IT
You know a lot of this. The plan starts from what the coach sees you do. Your time goes to the domains where you have shown the least — not to a course that re-teaches your day job.
Teaching or mentoring others
Every domain maps to the concepts underneath it, and each learner keeps their own record of the work they have shown. Use it to see where a cohort has shown the least before the exam window, not after.
