Worth getting the ACC cert if I'm a family caregiver, not a professional?

My mother was diagnosed with early-stage Alzheimer's two years ago and I've been her primary caregiver ever since. A social worker at her neurologist's office mentioned the Alzheimers caregiver certification and I'm wondering whether it's worth pursuing as a non-professional family member.

I'm not looking for a pay raise or a job change — I just want to be the best caregiver I possibly can for her. The caring for elders curriculum sounded comprehensive when I read about it, covering communication, safety, and behavioral support. Has anyone here done it purely for personal knowledge rather than career reasons?

I've been using the ACC practice tests to preview the material and they're already teaching me things I didn't know. Curious what the study time commitment looks like for someone without a clinical background.
