ICFSM exam day — what do you actually need to bring?

Scheduling my ICFSM - International Certified Food Safety Manager exam this week and trying to figure out what to actually bring vs what I'll be given.

Questions I have:
1. Do they provide scratch paper or is it on-screen only?
2. Are you allowed any breaks? The exam is 3 hours and I'm a slow reader
3. How strict is check-in? How early should I arrive?
4. Is a calculator provided or allowed?

I've been focused on studying "ICFSM" content but I realize I don't actually know what the test day experience is like. The official website is vague.

For those who took it recently — any surprises on exam day that you wish someone had warned you about? And did the difficulty feel similar to the practice tests or completely different?
