CPM certification — written exam questions and mentor log requirements

I'm working toward my Certified Professional Mentor credential and I'm in the middle of putting together my mentor log documentation. From what I understand, you need to show a certain number of logged mentoring hours before you're eligible to sit the written exam, and I'm trying to figure out exactly what counts and how detailed the log entries need to be. The official guidance is a bit vague on whether informal check-ins qualify or if every session needs a defined goal structure.

The written exam itself — has anyone taken it recently? I've heard it's about 100 questions and covers mentoring models, active listening, goal-setting frameworks, developmental relationships, and ethical boundaries in mentoring. I'm particularly curious about whether they test specific frameworks like the GROW model in depth or just expect general familiarity.

I've been a mentor through my company's formal program for about 3 years so I'm not going in cold, but formalizing that into a credentialed framework feels different from how I actually work with mentees day to day. I've got two active mentoring relationships right now and I've started logging sessions much more systematically — date, duration, topics discussed, agreed next steps — but I'm not sure if that level of detail is sufficient.

Any input from people who've already completed the process would be really useful. I'm hoping to sit the exam within the next 4 months and I want to make sure the documentation side doesn't hold me back.
