What's the actual passing score for CMRT? Getting conflicting info

Been searching for the CMRT passing score and I keep seeing different numbers. Some say 70%, others say 75%, and the official website isn't super clear.

I've been working through "CMRT" searches online and the passing requirement seems to vary by state or version? Or am I overthinking this?

My practice test scores are hovering around 64%. Should I be aiming higher before I schedule my actual exam?

Also I noticed on CMRT - Certified Marine Radar Technician — are the practice questions usually harder or easier than the real thing? Trying to calibrate how ready I actually am.

Any recent test takers who can share what the real cutoff is?
