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

Scheduling my (CAE) Certified Agile Essentials Specialist 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 2 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 "CAE" 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?
